Who's arguing that? Bush made tax cuts, the economy boomed, people were leary of putting money into the stock market so real estate took off, Congressmen put pressure on banks to let the little guy participate in the quickly rising equity, banks made millions of bad loans, Wall Street escalated it by creating derivatives based on those mortgages that few understood, tons of money poured in as greed escalated, then all those poor people started saying I can't afford this mortgage and mostly walked away when the market got so overheated there weren't enough buyers, it quickly escalated into possibly the biggest self inflicted financial disaster in the history of the world. And Obama said let's spend our way out of it and the national debt doubled(with Republican acquiescence!). And here we are today only Dems say it wasn't our fault and we should keep spending like nothing ever happened. Good luck with that!
