1577 people died in Louisiana from Katrina, not 300. And no not everyone who died were poor and black.
You don’t think Haiti’s death toll isn’t a little bit due to man? The corrupt government had no infrastructure or building codes. Instead of improving the infrastructure with the gazillions of aid money they have received over the years the corrupt government enriched themselves instead.
Of course Haiti is and always has been terribly corrupt. (So has Louisiana, to a lesser degree.) But Haiti is old, and many of the buildings in there were erected long before building codes were conceived. Even the US, building codes are not uniform, and few buildings outside of earthquake-prone areas are built to withstand earthquakes.
I think that if Haiti were more sophisticated and more developed, the toll might have been even higher, as more people would have been in large, heavy buildings rather than the pitiable shanty-towns where so many live. In those shanty-towns, the death toll has been small since the construction materials were so lightweight they could hardly injure someone if they fell. There was an article about that phenomenon today.
