There is the flood in Puerto Rico, a US colony since the late 18oos. The US did not allow waiting nations deliver supplies. Imports have to bow to the Jones act which means that imports must first come to the US and change boats to go elsewhere. What impoverished nation can afford the price of importation now?
Disaster did not start with the flood. There were years of underfunding governmental maintained things like electricity so that the island would fall apart when subjected to environmental stress. The governor allowed the Promessa Act so that when disaster strikes, he can kick natives off their underfunded jobs and allow foreigners to make the decisions and the money. The foreigners often lack training and understanding of the terrain and the job itself but they do know where the money is. Puerto Ricans without water and electricity die. Hospitals without electricity and supplies see patients die in great numbers. The current count is approaching 5,000. Those who can flee to Florida. This empty out of an occupied nation was planned for. Now non-PR millionaires can build hotels on the stolen beaches and create a vacation paradise.
Whenever you can’t understand some event, look at where the money goes.
