It can be argued that the Kennedy tax cuts paid for themselves. Other examples like the Baltic states that switched to a flat income tax and sales tax is more due to moving to something simple and more difficult to cheat.
Other than that, Laffer (famous for the Laffer Curve which was foundational to trickle down economics) and apparently the Kansas legislature are the only ones that think tax cuts for the rich help.
Has there ever been a case where tax cuts genuinely helped a country/state/whatever’s economy?
