Trickle-down economics

Imagine a world where prosperity flows like water — from the mountain peaks of the wealthy down to the valleys where everyone else lives. This is the core idea behind "trickle-down economics," a term often used to describe policies that disproportionately favor the rich and corporations, with the promise that benefits will eventually reach everyone else. But does this economic stream truly flow as intended, or is it more of a mirage? "Trickle-down economics" is a critical term for policies that reduce taxes or regulations for the wealthy, with the theoretical aim of stimulating broader economic growth. The concept, though not formally embraced by economists under this label, has a long history, appearing in political discourse and critiques of economic policy since at least the late 19th century. Economic analyses frequently show that policies described as "trickle-down" tend to increase wealth inequality without consistently delivering significant benefits to overall economic growth or employment.

AI Summary

Imagine a world where prosperity flows like water — from the mountain peaks of the wealthy down to the valleys where everyone else lives. This is the core idea behind "trickle-down economics," a term often used to describe policies that disproportionately favor the rich and corporations, with the promise that benefits will eventually reach everyone else. But does this economic stream truly flow as intended, or is it more of a mirage?

What is Trickle-Down Economics?

At its heart, "trickle-down economics" is a popular, often pejorative, term used to describe government economic policies that heavily favor the upper echelons of society — think wealthy individuals and large corporations. The idea is that by providing these groups with tax breaks or fewer regulations, they will invest more, create jobs, and stimulate the economy, with the benefits eventually 'trickling down' to everyone else.

However, critics of these policies, particularly those associated with supply-side economics or neoliberalism, strongly dispute this notion. They argue that such policies often widen income inequality, concentrating wealth at the top without significant benefits reaching those who are less fortunate or the economy as a whole.

The Horse and Sparrow Theory

Interestingly, no mainstream economist or major political party officially advocates for theories or policies using the specific term "trickle-down economics." Instead, it functions primarily as a critical label. One vivid metaphor for the concept, popularized by economist John Kenneth Galbraith, is the "horse-and-sparrow theory": if you feed a horse enough oats, some will pass through for the sparrows to eat.

A Long History of the Idea

While the term gained significant traction in the United States during the Reagan administration, the underlying concept of wealth flowing from the top down has been debated for over a century. The Merriam-Webster Dictionary traces the phrase "trickle-down theory" itself back to at least 1954.

Even in 1896, Democratic presidential candidate William Jennings Bryan touched upon the idea in his famous "Cross of Gold" speech, using the metaphor of a "leak" to describe how prosperity might or might not reach ordinary people. This shows the long-standing nature of the debate.

The humorist Will Rogers, in a 1932 column criticizing President Herbert Hoover's approach to the Great Depression, famously articulated the 'trickle-down' idea, albeit with a cynical twist. He observed that while water trickles down, money seemed to trickle up.

Rogers wryly noted, "The money was all appropriated for the top in the hopes that it would trickle down to the needy... But he didn't know that money trickled up. Give it to the people at the bottom and the people at the top will have it before night, anyhow." A truly fascinating insight into the public perception of economic flows.

Reagan and the Rise of the Term

The phrase truly entered the American lexicon with Ronald Reagan's presidency in the 1980s. Reagan campaigned on a platform of supply-side economics, which proposed that lower taxes and less regulation would stimulate production and investment, ultimately benefiting everyone.

Initially, even within the Republican party, there was skepticism. George H. W. Bush famously called Reagan's economic approach "voodoo economics" during the 1980 primaries. The term "trickle-down" then gained wider circulation after an interview with Reagan's budget director, David Stockman.

In this 1981 interview, Stockman candidly admitted that the "supply-side formula was the only way to get a tax policy that was really 'trickle down.'" This comment, linking supply-side policies directly to the 'trickle-down' concept, was quickly seized upon by political opponents to brand the administration's policies as favoring only the wealthy.

Modern Examples and Broader Usage

In the United States, major tax cuts under Republican administrations — such as the Reagan tax cuts, the Bush tax cuts, and the 2017 Tax Cuts and Jobs Act — are frequently labeled as "trickle-down economics" by critics. While these cuts often reduced taxes across all income brackets, the largest reductions disproportionately benefited the highest earners.

The critique isn't limited to income, either. Sometimes, the term is used to describe how positive externalities, like benefits from technological innovation or increased trade, might not accrue solely to the innovators but also "trickle down" to the broader population. However, this is a less common application.

The "trickle-down" critique has been echoed globally and across the political spectrum. Pope Francis, in his 2013 apostolic exhortation, condemned "trickle-down theories" as expressing "a crude and naïve trust in the goodness of those wielding economic power." He stated that these theories have never been confirmed by facts.

More recently, political figures like Hillary Clinton, who dubbed Donald Trump's tax plan "trumped-up trickle-down," and President Joe Biden, who unequivocally stated that "trickle-down economics has never worked," continue to use the term as a powerful political shorthand for policies they oppose.

Objections to the Term

Not everyone agrees with the use of "trickle-down economics" as a descriptive label. Proponents of supply-side economics, for instance, argue that the term misrepresents their theories. Economist Thomas Sowell contends that no serious economist has ever advocated for a "trickle-down" theory.

Sowell asserts that supply-side economics actually works in the opposite direction from the "trickle-down" caricature. He says that "Workers are always paid first and then profits flow upward later — if at all." This highlights a fundamental disagreement over the actual mechanisms of economic policy and wealth distribution.

What Do the Data Say?

So, what does economic analysis reveal about the effects of policies labeled "trickle-down"? Studies investigating the impact of lowering taxes on the wealthy have yielded significant insights, often challenging the core premise of the theory.

Nobel laureate Joseph Stiglitz, for example, argues that post–World War II evidence points not to "trickle-down economics" but rather to "trickle-up economics" — where economic benefits flow from the broad base of the population upwards through increased demand and consumption.

A comprehensive 2020 research paper by economists David Hope and Julian Limberg analyzed 50 years of data from 18 countries. Their findings were stark: tax cuts for the rich increased inequality in the short and medium term, but showed no significant effect on real GDP per capita or employment.

This suggests that the intended benefits did not broadly "trickle down" to the wider economy. The study further noted a dramatic divergence in wealth distribution from 1980 to 2016, with the top 0.01% of earners seeing a 600% increase in real income, while the bottom 99% experienced negligible change.

Even the International Monetary Fund, in a 2015 staff discussion note, suggested that lowering taxes on the top 20% might actually reduce economic growth. This counters the fundamental assumption that enriching the top will automatically boost the overall economy.

Political scientists Brainard Guy Peters and Maximilian Lennart Nagel have gone so far as to describe the idea that tax cuts for the wealthy stimulate growth benefiting the less affluent as a "zombie idea" — one that persists despite being repeatedly disproven by evidence. The debate, it seems, is far from over.

Trickle-down economics

Ronald Reagan's economic policies, dubbed "Reaganomics" by opponents, included large tax cuts and were characterized as trickle-down economics. Here, he outlines his plan for the Economic Recovery Tax Act of 1981 from the Oval Office in a televised address, July 1981.

Trickle-down economics, also known as trickle-down theory and the horse-and-sparrow theory, is a term used to describe government economic policies that disproportionately favor the upper tier of the economic spectrum (wealthy individuals and large corporations). The term has been used broadly by critics of supply-side economics to refer to taxing and spending policies by governments that, intentionally or not, result in widening income inequality; it has also been used in critical references to neoliberalism. These critics reject the notion that spending by this elite group would "trickle down" to those who are less fortunate and lead to economic growth that will eventually benefit the economy as a whole.

While criticisms have existed since at least the 19th century, the term "trickle-down economics" was popularized by Democrats in the US to derogate Reaganomics and its reduction in the top marginal tax rates.

Major examples of what critics have called "trickle-down economics" in the US include the Reagan tax cuts, the Bush tax cuts, and in the UK include Margaret Thatcher's economic policies in the 1980s and Liz Truss's mini-budget tax cuts of 2022.

History

Trickle-down economics

William Jennings Bryan used a similar phrasing ("leak through") to characterize his opponents who supported the gold standard in his Cross of Gold speech in 1896.

In 1896, United States Democratic presidential candidate William Jennings Bryan claimed in his Cross of Gold speech that his opposition based their policies on the idea that the success of the rich would "leak through" to the lower classes, stating: "There are those who believe that, if you will only legislate to make the well-to-do prosperous, their prosperity will leak through on those below."

In 1932, humorist and social commentator Will Rogers wrote a column criticizing Herbert Hoover's policies and approach to The Great Depression and stated: "The money was all appropriated for the top in the hopes that it would trickle down to the needy. Mr. Hoover was an engineer. He knew that water trickles down. Put it uphill and let it go and it will reach the driest little spot." In 2007, political commentator William J. Bennett credited Rogers for coining the term "trickle down" and observed its persistent use throughout the decades since.

In 1983, H. W. Arndt wrote that Indian nationalist and statesman Jawaharlal Nehru may have been the first to use the term in an economic (rather than political context) when he stated in 1933 "the exploitation of India and other countries brought so much wealth to England that some of it trickled down to the working class and their standard of living rose."

Samuel Rosenman, a Democratic presidential speechwriter under Franklin D. Roosevelt and Harry Truman, and coiner of the term "New Deal", wrote that "trickle down policies" had been prevalent in American government since 1921. In 1969, after leaving the presidency, Democrat Lyndon B. Johnson alleged "Republicans ... simply don't know how to manage the economy. They're so busy operating the trickle-down theory, giving the richest corporations the biggest break, that the whole thing goes to hell in a handbasket."

Ronald Reagan launched his 1980 campaign for the presidency on a platform advocating for supply-side economics. During the 1980 Republican Party presidential primaries, George H. W. Bush had derided Reagan's economic approach as "voodoo economics". Following Reagan's election, the "trickle-down" reached wide circulation with the publication of "The Education of David Stockman", a December 1981 interview of Reagan's incoming Office of Management and Budget director David Stockman, in the magazine Atlantic Monthly. In the interview, Stockman expressed doubts about supply side economics, telling journalist William Greider that the Kemp–Roth Tax Cut was a way to rebrand a tax cut for the top income bracket to make it easier to pass into law. Stockman said that "It's kind of hard to sell 'trickle down,' so the supply-side formula was the only way to get a tax policy that was really 'trickle down.' Supply-side is 'trickle-down' theory." Reagan administration officials including Michael Deaver wanted Stockman to be fired in response to his comments, but he was ultimately kept on in exchange for a private apology. Political opponents of the Reagan administration soon seized on this language in an effort to brand the administration as caring only about the wealthy. In 1982, John Kenneth Galbraith wrote the "trickle-down economics" that Stockman was referring to was previously known under the name "horse-and-sparrow theory", the idea that feeding a horse a huge amount of oats results in some of the feed passing through for lucky sparrows to eat.

In the 1992 presidential election, independent candidate Ross Perot also referred to trickle-down economics as "political voodoo". In the same election, during a presidential town hall debate, Bill Clinton, referring to the previous presidencies of Ronald Reagan and George H. W. Bush stated "...we've had 12 years of trickle-down economics. We've gone from first to twelfth in the world in wages. We've had four years where we've produced no private-sector jobs. Most people are working harder for less money than they were making 10 years ago".

Usage and reception

Trickle-down economics

In 1983, H. W. Arndt described the term as a myth, saying that no major economists of the 1950s assumed that wealth would accumulate among the rich and then spread to the poor.

Author and political commentator William Safire, in his political dictionary published in 2008, defined "trickle-down theory" as "The idea that aid to corporations will seep through to employees and irrigate the economy."

Thomas Sowell, a proponent of supply-side economics, says that trickle-down economics have never been advocated by any economist, writing in his 2012 essay "Trickle Down" Theory and "Tax Cuts for the Rich" that "[t]he 'trickle-down' theory cannot be found in even the most voluminous scholarly studies of economic theories." Sowell disagrees with the characterization of supply-side economics as trickle-down, saying that the economic theory of reducing marginal tax rates works in precisely the opposite direction: "Workers are always paid first and then profits flow upward later – if at all." In 2014, Sowell called trickle-down economics the "biggest lie in politics," and said "The time is long overdue for people to ask themselves why it is necessary for those on the left to make up a lie if what they believe in is true."

While the term "trickle-down" is commonly used to refer to income benefits, it is sometimes used to refer to the idea of positive externalities arising from technological innovation or increased trade. Arthur Okun, and separately William Baumol, for example, have used the term to refer to the flow of the benefits of innovation, which do not accrue entirely to the "great entrepreneurs and inventors", but trickle down to the masses. And Nobel laureate economist Paul Romer used the term in reference to the impact on wealth from tariff changes. The Laffer curve is often cited by proponents of trickle-down policy.

Benjamin Lockwood, professor of business economics and public policy at Wharton, said "The term ‘trickle-down economics’ doesn't really represent a cohesive economic theory,” “It's a term used, often negatively, to characterize the view that reducing taxes on the rich will benefit the non-rich.”

The political campaign group, Tax Justice Network has used the term referring broadly to wealth inequality in its criticisms of tax havens. In 2013, Pope Francis used the term in his apostolic exhortation Evangelii gaudium, saying that "Some people continue to defend trickle-down theories which assume that economic growth, encouraged by a free market, will inevitably succeed in bringing about greater justice and inclusiveness in the world."

In New Zealand, Damien O'Connor, an MP from the Labour Party, called trickle-down economics "the rich pissing on the poor" in the Labour Party campaign launch video for the 2011 general election. In a 2016 US presidential election candidates debate, Hillary Clinton accused Donald Trump of supporting the "most extreme" version of trickle-down economics with his tax plan, calling it "trumped-up trickle-down" as a pun on his name. In his speech to a joint session of Congress on April 28, 2021, US President Joe Biden stated that "trickle-down economics has never worked". Biden has continued to be critical of trickle-down.

A Columbia journal article comparing a failed UK Enterprise Zone proposal to later US proposals references them as a form of trickle-down policy where lower regulatory and tax burdens were aimed at wealthier developers with the hope they would benefit residents. Nobel laureate Paul Krugman states that despite the narrative of trickle-down style tax cuts, the effective tax rate of the top 1% of earners has failed to change very much. Political commentator Robert Reich has implicated institutions such as The Heritage Foundation, Cato Institute, and Club for Growth for promoting what he considers to be a discredited idea. Kansas governor and politician Sam Brownback's 2018 tax cut package was widely labelled as an attempt at trickle-down economics. Friedrich Hayek's economic theories have also been described as trickle-down.

In 2022, the Liz Truss administration objected to characterizing its policies as "trickle-down economics".

Studies and research

Trickle-down economics

In 2015, Joseph Stiglitz wrote that in the 1950s and 1960s in industrialized nations, all levels of workers were gaining, with lower income workers experiencing the most gains, political theories of "trickle-down" associated with the "a rising tide lifts all boats" hypothesis were believed. He stated that the data equally supports the ideas of "trickle-up" theory, or "build out from the middle" theory.

In a 2020 research paper, economists David Hope and Julian Limberg analyzed data spanning 50 years from 18 countries, and found that tax cuts for the rich increased inequality in the short and medium term, and had no significant effect on real GDP per capita or employment in the short and medium term. According to the study, this shows that the tax cuts for the upper class did not trickle down to the broader economy. From 1980 to 2016, a divergence in the distribution of wealth was noted, with the top .01% of earners seeing a 600% change in real income, vs a 0% change in the bottom 99%, leading to the top 1% accruing 15% more of the total wealth pool, from a share of 15 to 30%.

A 2015 IMF staff discussion note by Era Dabla-Norris, Kalpana Kochhar, Nujin Suphaphiphat, Frantisek Ricka and Evridiki Tsounta suggests that lowering taxes on the top 20% could actually reduce growth. Political scientists Brainard Guy Peters and Maximilian Lennart Nagel in 2020 described the 'trickle down' description of tax cuts for the wealthy and corporations stimulating economic growth that helps the less affluent as a "zombie idea" and stated that it has been the most enduring failed policy idea in American politics.
