who will pay for rebuilding if the gulf coast is hit by Gustav

I am fairly concerned that there won't be any funds for rebuilding if the gulf coast states are hit. Especially since many of the areas in Mississippi are still like a war zone with little or no help. People are still living in the FEMA trailers in some areas.

Where will the USA get the money to help these people? More empty promises with displaced people in god knows how many states?
