Yet…liberal (keynesian) economics were in place when the middle class did its best…(1945-1981 (of course there were other factors as well) There were not massive wealth gained during that time…a lot of people doing well…but not morbidly rich like we have today.

Not enforcing the Sherman act, deregulating the banking systems (which blew up in the late 80’s and then 2007), trashing unions, allowing monopolies to grow, legalizing stock buybacks…and more…all contributed to the current situation. Trickle down, and deregulation…work well…for the ultra rich.
