You're ignorant and delusional with that statement. Any basic understanding of history and economics proves the existence of economic mobility. It can be fucked up through excessive government regulation, taxation, and--recently--bailouts of politically-connected businesses with the "too big to fail" mantra, but there are no set classes in the United States. Wealth can be created and obtained just as it can be lost, and there is no system more accommodative of growth than capitalism. Take Microsoft, Apple, Google, UPS, FedEx, any transportation company, any service industry chain, any medical business, or any business for that matter. There is growth that started with one dude in his garage with a brilliant idea, and failure from a company that could no longer sustain business. Otherwise, the United States, and most developed countries would be nothing more than medieval serfdoms with subsistence farmers with a few thuggish lords self-appointed as rulers.
Obama is "moderately conservative" compared with Marxists like the Bolsheviks, Maoists, and their ilk who propose violent revolution for egalitarian collectivism. Otherwise, he is a collectivist and a statist who aims to achieve egalitarianism through government redistribution of wealth. Listen to his statements, research his voting record, examine his economic policies, and read Marx or whatever classical statist and collectivist philosophy to match up the ideology and goals. Open your mind, research, and you'll come to understand.
And, don't waste your time with Fox News quips. I couldn't care less about them these days. The majority of their programming is as vapid as the rest of the cable news networks, and they're half overrun with Bushies and crusty, old guard Republican elite for guests analysts.
