“Trickle Down” Theory and “Tax Cuts for the Rich”

He demonstrates that no serious economist has ever advocated a literal “trickle-down” theory. Instead, advocates of lower marginal tax rates argue that reducing high tax rates improves economic incentives for work, saving, and investment—leading to broader economic growth and increased tax revenues from upper-income groups.

Drawing on extensive historical evidence (including the tax cuts of the 1920s, Kennedy, Reagan, and others), Sowell shows how these policies often expanded the tax base and benefited the overall economy. The essay critiques media and political caricatures of supply-side economics and emphasizes empirical outcomes over rhetorical straw men. Published by the Hoover Institution in 2012.
