wut, the government damn near subsidized the middle class into existence after WW2. How you think the lily white suburbs filled with "independent" Americans came about? FHA loans are just the most obvious example. I remember reading some white dude bought a $15,000 house for $600 in the 1940s.
But anyway, I'd agree that today the government doesn't help the middle class out enough (if by middle class you mean white-collar employees who possess lots of human capital through their degrees). They state has to do a better job at keeping corporations rooted in place, so skilled jobs won't migrate elsewhere. Ask Detroit: once corporations run away, the economy of any place just will not do well. They also gotta do a better job supporting some kind of unionization: a lot of the old heads are getting dismissed in favor of younger workers. But for this to happen the middle class gotta mobilize behind politicians who will actually embrace this as a platform. People like to pretend like we don't live in a democracy in which we have the right to vote.
