Post WWII we were paying a top rate of 93%, and it was one of the most prosperous periods in our history! We need to rethink the whole "lower taxes, improve the economy" idea. Income inequality does NOT improve the economy. Lowering taxes on corporations and the rich only makes that worse.

Even the original Laffer Curve stuff said that if you lower taxes, the government collects more (up to a point). But note that it didn't ever say "lower taxes and improve the economy". It just makes rich people richer, and takes away government services the poor need. The only "trickle-down" you feel on your head is some rich guy pissing on you. Which is exactly what the Trump tax cut did and will do in the future to Social Security and Medicare.
