Of course the one problem is the lost tourism, which will be gone forever in a new location.
Historic district.
It works great in Tombstone.
Oh wait.
Right, alot of it will be lost, much of it forever. That's what makes the rebuild so crucial. I would go to visit a rebuilt NOLA, it won't be quite the same, but it can be recaptured kind of the way Europe rebuilt after WWII. I've never seen the original and now I won't be. To really recover, a fast, safer rebuild to try to woo lost tourism. Otherwise it's just a nice lake.
I don't know how all those people will get by without their jobs and all their possessions lost. They had entire 'poor' parishes, now how many more will be newly destitute? I can't imagine. They say a lot didn't have, or couldn't get!, flood insurance. That will be one giant stumbling block in rebuilding the tourist area. It will affect, I believe, our nation's economy and not just because of the oil. I'm not an economist, but I think the theories of trickle down economics and macro-economics as it pertains to our nation can be seen working here. Already the Landrieu types have their talons out and are pointing fingers of blame, instead of working on ways to rebuild and get the place running again, which will ultimately benefit her citizens in ways far greater than any government relief, although much needed, ever could. I guess it's the old battle between the nanny state dems and the republicans.
