When I say that every hurricane policy is written in blood, and deaths in natural disasters are largely political choices, that's what I mean. The 1935 Hemingway essay could have just as easily been written about Katrina or any number of other storms, with just the details changed.
Incidentally, the argument Hemingway made that sending Bonus Army vets to the Keys during hurricane season was murder is a disturbing parallel to Ron DeSantis and Donald Trump putting immigrants in tents in the Everglades during hurricane season. It's attempted murder even when the attempt fails.
