As well you should; it's a great idea.
Here's more: Of the 500,000 people (or is it families?) who've been dislocated, I'll bet 90% of them are within 200 miles of N.O.
Now, imagine the effect on the local construction industry of hundreds of thousands of people, with cash, wanting new houses. Imagine the ripple effect through the economy. It wouldn't stop there. All these people with mortgage-free homes would want to furnish those homes, with furniture and applicances. Maytag would have to keep its factories going triple shifts to be churn out enough washers to meet the demand. The nation's unemployment rate would drop to a tiny fraction of one percent and Bush would be hailed as the nation's savior because he wouldn't sign the Kyoto Treaty and caused the global warming that brought Katrina. The Constitution would be amended to allow presidents to serve unlimited terms, and Bush would be re-elected in 2008, becoming the first presidential candidate to carry every single state, to Shemp's undying fury.
Win-win.
