Why can't the government simply payoff everyone's mortgage to resolve the housing crisis? 
Government purchases of mortgages simply transfers the debt burden from households to the sovereign. Taxes pay sovereign debt (65% of whom are homeowners anyway). No debt has been restructured -- it's now paid via taxes instead of monthly mortgage payments -- and those paying include persons who responsibly avoided housing speculation. The U.S. has a debt-to-GDP ratio just shy of the critical point of 90%. Purchasing $10 trillion in mortgage debt (about a year of GDP) would put the U.S. on an inexorable path towards insolvency and inflation. There are all sorts of other risks (loss of a risk-free asset, moral hazard, nationalization of the housing industry, etc.) but this should make the point clear that it's not a good idea. There are only three ways to reduce debt: 1) default, 2) restructure, or 3) lower the real debt burden by de-valuing currency in which the debt is denominated.
