Politico has a good summary of the U.S. response to hurricane damaged destroyed Puerto Rico. I think the story confirms my own summation. We responded differently to Puerto Rico because it was "too poor and too dark (as in brown)." Our government responded more effectively to Texas and Florida because the residents were wealthier and more white. And five years from now both areas will be whiter and the wealthier areas will be largely rebuilt while the darker areas languish. Look at post-Katrina New Orleans.
