Interesting that you single out US/UK.    

The origins of Haiti's problem are clearly France.      In 1804 the Haitians basically slaughtered all of the French masters and left the country completely without leadership or organization.  France did not set up any system of governance like the British , Dutch or Spanish.

France has never paid Haiti back the 21 Billion (40B in todays money) that France illegally took (90 million gold francs) to let Haiti declare independence.   Haiti has never recovered from the weight of this debt.

How lucky we in Canada are that we fell under British colonization after the British victory on the plains of Abraham in 1759.

There are no successful French nations that are now prosperous countries and many disasters.   Haiti, Vietnam, Cambodia, most of Africa. 

Even in our own country... Quebec  is using French civil law governance rather than British parliamentary system and is forever a have-not province.
