Which policies that Obama has enacted has caused this to happen? Specifically and how?
Correct: This is what Obama meant by change....
I am no Obama fan but let's not deny factual reality. This economic crisis was prepped by the Reagan Administration and the Bush Administration nearly put the finishing touches on it. I fault Obama for not taking more aggressive action to repair the damage but there is no question that the Republicans in Congress have done all they could to impede him and to sabotage everything they could in the way of repair.
Obama is no FDR but he is a vast improvement over the elitist, corporatist sonofabitch he succeeded. With another Republican in Office we would be doing a lot worse.
What America needs now is a very strong socialist agenda to reverse the efforts of the right-wing corporatocracy, to constrain the bankers, and to rid us of the Wall Street sharks. We need to stop locking up pot dealers and start prosecuting those white-collar criminals who have methodically undermined the American Middle Class and damaged our Nation. Obama failed to do these things but I'm quite sure McCain wouldn't have done them either, nor would Romney. The only presidential candidate whom I believe would have and could have done those things is Dennis Kucinich. But he is an angry, unattractive little man.
