it's pretty easy to find the years that economic policies were enacted and objective data of the economy. For the most part there's no strong correlation between any of it.

for example here are some graphs comparing things like US gdp, top bracket tax rates, corporate tax breaks, corporate profts, government spending and revenues, years of recessions, etc.

tax rates vs gdp

corporate tax rates vs corporate profits

tax rates versus changes in personal saving

federal receipts and expenditures normalized to GDP compared to years of recessions

As we can see, how high our taxes are, how much the government spends, and the ratio of spending to taxes all seem to be irrelevant to how our economy actually functions. The debates about which president helped or hurt the economy is roughly analogous to wondering whether Zeus or Thor caused the last thunderstorm.
