This has nothing to do with the political effect of Katrina. The chaos in New Orleans appears to be quite simply an issue of the moral quality of the population - America's Burden, so to speak.
A piece of evidence supporting this view was recently published on Prestopundit. It is a report by a lady who volunteered at a Texan relief center:
I know they have just suffered a lot and lost everything, but that’s really no reason to take advantageous of people’s generosity. I swear it’s like they didn’t have any home training. Some of these people don’t have any sense of common decency or respect for fellow human beings; especially those who are trying to help him.
To which one can only observe:
Wherefore by their fruits ye shall know them.
Matthew Chapter 7 v. 20
