The only way to prevent a CRA-induced crash around 2005 was to open the floodgates of fraud to prop up the housing market. Blame the people who decided it would be better to open the floodgates than be caught in a small crash, but were it not for CRA-induced malfeasance, there would have been no driving motivation to open the floodgates to the upcoming major crash.
Just post I don't know c+++ about supply and demand and you would be better off. Greed has aways been the driving force.
