My sister lives in Houston. I don't remember the name of the hurricane, but I think it was the year after Katrina.
When the power went out and was expected to be out for several days, there was no looting in her neighborhood. The homeowners got the food of of their freezer, pulled out their grills and hosted one giant neighborhood block party. It was actually sort of fun and made use of a resource which otherwise would have gone to waste.
As a bonus, all the people in the streets for the big block party kept any looters from outside the neighborhood out.
She also told me that when some of the NOLA residents camped at the Astrodome had worn out their welcome, Houston set up a limited time offer to get most of them one way airline tickets out of town.
We had a good hearted family friend in rural Montana who offered to host one of these families and couldn't believe how jaw-droppingly shiftless they were.
After about a week, they told them to either start helping with the family chores (nothing difficult, just routine stuff any rural family does from the time the kiddies are able to walk) or find another place to live. They took the one way bus ride out of town instead.
Many of the people I talk to from church groups that went to NO to help after Katrina, complained that much of their time was wasted filling out government forms (FEMA) for these people so that they could get free stuff. Then they loudly complained when stuff was slow to arrive.
47% of the people in the city of NO cannot read or write...just like Detroit.
(I guess reading/writing is acting to White)
A lot of refugees from New Orleans went to Camp Chaffee in Fort Smith, Arkansas.
There was an offer / request for volunteers to go there to help out as hosts to the refugees. The reality was that they wanted people to be servants for the refugees. Cook, clean, clean bathrooms, make beds etc. All things the able bodied refugees could have done for themselves.
Not all but enough of the refugees were abusive to the point of FORGET IT and I’m out of here by all the volunteers I knew of. It was a pitiful mess.
Changing the course of the Mississippi and abandoning NOLA would be a good idea but for the economic damage that would be created to the industries along the river. NOLA is a crap hole.
