Every time a bubble bursts, the goverment is desperate to create a new one.
The .com bubble was replaced by the housing bubble. The housing bubble has been replaced by the treasury bubble.
"Keeping people in their houses" means that housing prices won't reach fair market prices. Irresponsible people are subsized to keep them in their houses, and these subsidies are making houses artificially expensive, which keeps responsible people like me from being able to afford them.
If only I had been irresponsible enough to rack up huge amounts of home equity debt, I would be living really well right now.
