It would have been cheaper yet just to set up those big tents and a couple hundred cots. I'll bet within weeks they would have their homes fixed to the point they could live in them instead of waiting years for the house to be completely ruined and expect the country or Brad Pitt to come in and build a new one for them for free.
I'm sorry for the first year I felt sorry for those folks but I was in NOLA this spring, most of those homes should have been razed, and then the rebuilding could have began, now they all just wait, and wait, and wait. For what? City state and Feds are all broke. It will be along time before that parts of that city are back to the dump it was before the storm.
