Who were those culprits? They were the politicians and government agency (read "FED") people who kept interest rates too low for too long. They were the bankers and mortgage brokers who relaxed their credit rules and wrote the ridiculous contracts, and the rating agencies who lied about the value of the packaged securities. They were the real estate agents who got rich peddling overpriced property to people who clearly could not afford it. All these big players made it possible for speculators and ignorant buyers to get hooked and subsequently get busted, and for the rest of us to bear much of the cost.
My gentle reminder is that the culprits mentioned above, the self-described champions of the "free market", are the perennial backers of the republican party. Their goals have not changed; they want want low taxes on their income and investments, and they want gentle regulation of their business interests. Many of them made big money during the boom years, and they kept it. Now they're trying to convince us that the people who got displaced by the crash don't need any more "welfare" and that the rich can't afford a tax increase. After what these people did to all of us during the Bush years, is it really possible Americans will hand them the reins again?
