The city of New Orleans was a city of over 1 million before Katrina. The city now has less than 300 thousand residence. One person had the power to bring much more attention to the wasteful spending even if he did not have the power to stop it... the Mayor Ray Nagin. And here the race separation begins. White residence hate the man with a passion and vocalize this often. African-Americans residence view him as the cities last hope. Why the two different views... well you must look at the make up of the city and who has power within the city. Before Katrina the city residences were majority African-American and those elected to lead and be in power mostly came from that majority. Now with over 700,000 removed from that mix there is no easy majority for either white or African-American. The shift of power in the city government is about to happen. That scares the old majority. Change scares many people.
What New Orleans will look like after all of this has passed, no one can know. What it looks like now is the poor being forced out because they can not afford to rebuild, the wealth reclaiming much of the city as the poor leave, and those in the city government getting even wealthier from all the corruption. I guess some things never change.
