Plus, people raise the insurance costs, and rebuilding house, businesses, etc. How will this NOT be a cost if we don't rebuild it? Insurance will still need to be paid out, housing will still need to be built to accomodate the refugees, no matter where they go. Business will need assistance restarting wherever they relocate to. Either way, the costs will be high. New Orleans should be rebuilt, but this time, listen to the people that say the levees couldn't handle a cat 3 storm or higher. If the levees were built right to withstand a storm surge of 25+ feet, instead of 10-15' there'd be no flooding in the city like you see now. There be some flooding, wind damage, but how will that mean it's not to be rebuilt? Why did we rebuild southern florida after andrew, san francisco after the fire of 1906, the gulf coast after camille?
