Nicholas Kristof has a column in the New York Times suggesting that for-profit businesses may do more to help Haiti than charities:
What Haiti needs above all these days is these kinds of livelihoods for its people, not just shipments of food and clothing. It's hard to think of a charitable project that will be as beneficial as the Coca-Cola Company's decision to build up the mango juice industry in Haiti, supporting 25,000 farmers. The same is true of the move by South Korean garment companies to open factories in Haiti.
