Having lived through Katrina, I have zero sympathy for people in Louisiana. First, every one of them could have bought flood insurance, which is subsidized by people who don't live in flood zones. Congress was going to change that after Katrina, but the law was blocked and defeated. Second, even if you can not afford to put your house up on blocks, in order to buy insurance, you always have the option to move to higher ground, or better yet, clean out of the state, like I did. My x-wife, on the other hand, chose to stay, in spite of having to leave her house in a rowboat in 1965 with Betsey, and being flooded out by Katrina in 2005. I am sure that neither she or her family would even consider moving to Hattiesburg, only about 1 1/2 hours away, and all but immune to floods, even after this week's disaster..
