That’s the first thing I thought of as well. The Dominican Republic is thriving while having a population descended from slaves. They behave differently and
expel Haitians when they find them.
I don’t know if it’s true but I read that Haiti’s real historical problem is that it was run by pirates for a long time. That’s their culture.
Haiti killed all the white people on the island after they won their independence. Women, children, and men. That killed any good will from other countries and doomed them from the start...
