Simple enough to understand. The average homeowner used their house as an ATM. Some of that due to greed and the need for immediate gratification. Most of it due to the fact that Joe Lunch Bucket has been working for slave wages since the 80's. Now add that if Joe has bought a house in the last 5 years, he's upside down and the rest have lost value. All are unlikely to see decent returns on that investment for a decade or two. Kick in massive unemployment and you have a recipe for disaster. Bottom line, if Joe doesn't have a job, it doesn't matter what the price or interest rate is...he ain't a buyer. Along comes Uncle Sugar to artifically prop up the market, but how long can that last? Taxes going up for those that still have a job and businesses which still employ are hesitant to hire because of those upcoming taxes. Average Joe takes it up the ass again. Now for the money boys, price coming down is just another windfall in the ever popular game of priviteizing gains while socializing losses. Nice scam, eh?
