I think the US should help aid a rebuilding of Haiti, but better yet I think it would be beneficial if we invested in Haitian companies and helped build their economy through capitalism and trade. If the US eternally funds Haiti then people will say that we are trying to take them over, and if we do nothing people will say that we are heartless war mongerers (The US can never truly win in these situations, kinda like Italy saying we help to make us look good and Chavez saying we used an earthquake machine to destroy Haiti so we can take it over ).
Also, we need to encourage a strong free market economy within Haiti and maybe "forcefully encourage" a good Haitian government. All the leaders they've had have been corrupt beyond all measure, it's primarily the fault of their government for Haiti being an impoverished nation. I went there in 2007 and the president was given millions of dollars from the US and Canada to build housing in Port Au Prince (definitely enough money). He put up a steel frame for the building and then ran out of money (gee, I wonder how?) Then he asked for more saying millions weren't enough.... I saw those steel frames too, they looked like an amateur built them. The Haitian government needs to be the first thing that changes, it really ticks me off with how corrupt they are and the injustice that is done towards the people.
