The other thing most often forgotten was when Reagan cut taxes in 1986 the top marginal rate was 70% and the economy was truly in the toilet. His tax cuts did have some positive impact and it could be reasonably argued that 70% really was too high and needed to be lower in order to stimulate the economy. Still, his tax cuts only brought the top rate down to 50%.
Mostly however, his dramatic increase in military buildup was the primary driving stimulus effect - not tax cuts.
Republicans have had 30 years to prove supply-side economics work and it’s very clear that the whole concept is bullshit.
