Honestly, this is the crazy part of all of this. The middle class was built on a bigger tax burder on the wealthy, which led to the largest epoch in human advancement (with a lot of caveats, yes -- but there's a lot of positives there).
Rolling back these tax rates has led to recession after recession and ever increasing gaps between the 1% and everyone else, and the middle class is shrinking.
It doesn't seem like it's such a hard line to draw between all of this.
