My mother used to do some work for an NGO, travelling to "third world" countries and writing reports for them. She would get a free trip and would be paid a small sum, maybe $1500. She visited many places, Mexico, India, Cuba, Nicaragua, Honduras, Nepal and, yes, Haiti, among others. Her trip to Haiti was about 25 years ago. At that time she found the people quite pleasant and although they were warned to stay in the hotels after dark, she got the same warning in most of the places she went. She also said the poverty there was greater than any other place she had been. For instance, she bought a couple of pieces of local "art" from one of the street sellers. They were simple pieces of tin or steel, pounded flat and then shaped and painted. They were maybe $1US. In talking to the man he told her that he was limited in the size of his pieces. If the metal was of a certain size, it was more valuable as building material than street art. An oil drum split and flattened, a street sign torn off a pole, any piece of sheet metal was used to build shanties. With poverty that widespread and no government to speak of, as it is now, people are gonna eventually reach a point where the dark side of human nature takes over. I once read a quote that "civilization is only 3 meals thick". Maybe an exaggeration, but the point is solid. Didn't take long before people realized that groups of people, gangs, were better at relieving others of their possessions than going solo. So, you get competing gangs terrorizing anyone that can't stand up to them. And, after being victimized by gangs a couple of times, it seems like a good idea to join a gang, just for protection.
Barring some pretty draconian crackdowns by a functional, supported government, or an uprising among the regular citizens, it's going to stay that way or get worse. Either way a lot of people will die.
