I only have two things in my life, my family and work. If there's any time left over, then I play sports.

It has become fashionable to rail against government intervention in the economy, and the FHA is a favorite example by those trying to show the government's overreach. In reality, the FHA shows how government action during the Great Recession forestalled a much worse economic fate.

Housing was ground zero for the Great Recession. Between early 2006 and Obama's inauguration in 2009, average house prices fell by a third across the country. In certain areas, including cities as diverse as Akron, Orlando and Las Vegas, house prices fell by more than half.

The key to house prices is the share of foreclosure or short sales in the total housing market. When that share rises, house prices will fall, because distressed properties sell for significantly less - currently around 25 percent below non-distressed houses.
