Went to a friend's wedding in 2007. One of the guests worked at CIDA (Canadian International Development Agency). I asked the guest as many questions as I could. There was a preliminary research trip before a Canadian official made her visit to Haiti. The purpose? To geolocate and photograph the facilities. And when I say facilities, think toilets. Making sure the white Canadian could poo-poo comfortably counted as aid.
Sure Haiti is incredibly corrupt, I remember that one of the ex-president's (Not Aristide) was head of the local kidnapping ring in Port Au Prince. But that's just small stuff. America and Canada use Haiti like it's their own toilet and want it to remain that way, in spite of the intentions of a select few and the limited posturing to the contrary.
One of the most disturbing things for me is to look at Hispaniola on Google Maps. The Dominican Replublic is lush and green. Haiti is a greyed out ####-hole.
I could go on and on, but reading up on an actual humanitarian in the region, Dr Paul Farmer, and his publications is a good start: https://en.wikipedia.org/wiki/Paul_Farmer
