Daniel Gross :
The U.S. economy needs the dynamism that renting enables as much as—if not more than—it needs the stability that ownership engenders. In the current economy, there are vast gulfs between the employment pictures in different regions and states, from 12% unemployment in Nevada to 3% unemployment in North Dakota. But a steelworker in Buffalo, or an underemployed construction worker in Las Vegas, can't easily take his skills to where they are needed in North Dakota or Wyoming if he's underwater on his mortgage. Economists, in fact, have found that there is frequently a correlation between persistently high local unemployment rates and high levels of homeownership.
