one more point...after pondering a bit, I realize I was 'thinking' poor & marginalized when I typed 'unemployed'. Even though some of those people had jobs of sorts, they might have a better life in other parts of the south...or even the country as a whole. The point is, a large 'underclass' who can't evacuate easily is a problem for a city with New Orleans' problems...even if they ARE employed.

The total population of the country, the state and the cities needs to be reduced, but that's a different, though related issue.
