Remember, the Haitians made a deal with the French to pay them an indemnity for their slaves ~ and it took them 100 years to pay off the indemnity.
That's not Socialism, but it had pretty much the same effect, so when the Socialists came around to "improve Haiti" they'd already been ground down so thoroughly it couldn't get better ~ ever ~ and it hasn't.
The French should repay them the $22 billion indemnity.
The Duvaliers killed off Haiti’s middle class via the Tonton Macoutes, because they tended to be lighter-skinned Creoles.
