Home loans didn't bring on the recession; gimmicky financial instruments bloated to 100 times their value are what caused all this pain.
Wall Street turned a few million home-loans into what Warren Buffet called "economic weapons of mass destruction," cratered the global economy and then, when the bubble burst, turned around and insisted on a massive bailout courtesy of the American tax-payer.
The entire subprime mortgage market was worth only $1.4 trillion in the fall of 2007, and that includes loans that were up-to-date. As former Goldman Sachs trader Nomi Prins noted in her book, It Takes a Pillage: Behind the Bailouts, Bonuses, and Backroom Deals from Washington to Wall Street, the federal government could have bought up every single residential mortgage in the country – good, bad and in between – and it would have cost a trillion less than the bailouts.
Short of that, notes Prins, if the crisis were really about people buying McMansions that they couldn't afford, “we could have solved it much more cheaply in a couple of days in late 2008, by simply providing borrowers with additional capital to reduce their loan principals. It would have cost about 3 percent of what the entire bailout wound up costing, with comparatively similar risk.”
What brought down the global economy was as much as $140 trillion worth of financial gimmickery built on top of the mortgage industry. It was the alphabet soup of the credit meltdown – the CDOs, default swaps and other derivitaves that made less than a trillion dollars of foreclosed loans into an economic weapon of mass destruction that would cost the American economy alone $14 trillion in lost wealth.
