People, get real. There are still thousands of misplaced U.S. citizens from disasters along the Gulf coast including families from Katrina. Take a look at New Orleans, it basically a ghost town. FEMA never came through for them, the promises were left unkept, and their insurance companies took them for a ride either up front on the policy or after the disaster.
I won't go on with the statistics and the stories you can look them up yourselves.
Never rely on the government for anything. The best lesson I have learned from my years living here is to be responsible for myself.
Funny someone mentioned the earthquake in Mexico City. The government owes no one a new house for a disaster caused by Mother Nature. Just like those living on coastal waters, to think someone owes you something for a decision you have made is way off course.
What Mexico should do is discourage people from moving to the Big Tamal as one day, who knows when, the really big one is coming.
Move away from coastal waters, it's not going to get better whether it was caused by man, nature or a combination of the two.
