If she had said something like "They were in horrible conditions in flood and hurricane-ravaged New Orleans, so coming to the Astrodome is working out much better for them" then I don't think anyone would have a problem with it. The Astrodome is working out much better for them than the Superdome and trying to survive in the disaster area.

But that isn't what she said. With typical Bush family obliviousness, she said "And so many of the people in the arena here, you know, were underprivileged anyway, so this--this (she chuckles slightly) is working very well for them." This implies that living in cramped conditions in the Astrodome with just the clothes on their backs is working out better for them than being poor underprivileged people living in their own homes in New Orleans in their own town with their families etc. Homes and lives are now utterly destroyed along with all of their possessions. Uh huh. Typical Bush, completely disconnect from reality.

So in that sense, yeah, it does ring a little like Marie Antoinette's oblivious suggestion that cake is available and the starving poor can eat it - as if that was the only problem.
