Yes they should have.
Haiti’s poverty seems a mixture of France’s brutality, France putting huge amounts of debt on it but also corruption, military coups and not building its people resources.
France hasn’t owned it for centuries. Corruption is the leading cause of problems in that poor nation. What has to happen is for one set of bandits to take over and establish order. Papa Doc was an awful tyrant but there was order—now we see what is worse than a dictator—no government at all. It seems when ever they get a good leader—he is killed. Haiti must solver her own problems and reach its own form of Government. They may need to go communist—or put back a king or fascist leader to rebuild—But it must come from them! How many times have we invaded over the centuries? It never works.
