The same has taken place in Haiti, which the IMF forced open to imports of highly subsidized U.S. rice at the same time as it banned Haiti from subsidizing its own farmers. Between 1980 and 1997, rice imports grew from virtually zero to 200,000 tons a year, at the expense of domestically produced staples. As a result, Haitian farmers have been forced off their land to seek work in sweatshops, and people are worse off than ever: according to the IMF’s own figures, 50 percent of Haitian children younger than 5 suffer from malnutrition and per capita income has dropped from around $600 in 1980 to $369 today.

Interesting topic. I've read about this before in regards to clothing donations to Africa.

But why gang up on a guy who just wants to help clothe people in Africa? First, because it's not that hard to get shirts in Africa. Flooding the market with free goods could bankrupt the people who already sell them. Donating clothing is a sensitive topic in Africa because many countries' textile industries collapsed under the weight of secondhand-clothing imports that were introduced in the 1970s and '80s. "First you have destroyed these villages' ability to be industrious and produce cotton products, and then you're saying, 'Can I give you a T-shirt?' and celebrating about it?" says James Shikwati, director of the Nairobi-based Inter Region Economic Network, a think tank. "It's really like offering poison coated with sugar."

Although, one would think, how could getting commodities in mass for free be a bad thing? Couldn't those textiles workers figure out another more productive way to spend their time and everyone's quality of life improves?
