No. I have spoken to several people who live in the Houston area and have lived there pre-Katrina. They have seen the influx of minorities that scrambled to the area post-Katrina. Apparently, all you have to do is mention/prove that you were a "victim" of Katrina and you are moved to the top of housing and employment lists in Eastern Texas. Couple that with other government welfare programs and there is no incentive for a majority of "victims" to return to New Orleans now, let alone if another hurricane hit. Again on has to remember that the hurricane did not do the majority of the damage, it was the failure of the levee system. A level 3 hurricane would likely not reproduce the type of damage seen during Katrina, simply because of the levee situation wont be reproduced.
