Haiti's vulnerability to natural disasters, its food shortages, poverty, deforestation and lack of infrastructure, are not accidental. To say that it is the poorest nation in the Western hemisphere is to miss the point; Haiti was made poor--by France, the United States, Great Britain, other Western powers and by the IMF and the World Bank. . . .
. . . the impoverishment of Haiti began in the earliest decades of its independence, when Haiti's slaves and free gens de couleur rallied to liberate the country from the French in 1804. But by 1825, Haiti was living under a new kind of bondage--external debt. In order to keep the French and other Western powers from enforcing an embargo, it agreed to pay 150 million francs in reparations to French slave owners (yes, that's right, freed slaves were forced to compensate their former masters for their liberty). In order to do that, they borrowed millions from French banks and then from the US and Germany. As Alex von Tunzelmann pointed out, "by 1900, it [Haiti] was spending 80 percent of its national budget on repayments.". . .
In 2003, then-President Aristide called on France to pay restitution for this sum--valued in 2003 dollars at over $21 billion. A few months later, he was ousted in a coup d'etat; he claims he left the country under armed pressure from the US.
Then of course there are the structural adjustment policies imposed by the IMF and World Bank in the 1990s. In 1995, for example, the IMF forced Haiti to cut its rice tariff from 35 percent to 3 percent, leading to a massive increase in rice-dumping, the vast majority of which came from the United States. As a 2008 Jubilee USA report notes, although the country had once been a net exporter of rice, "by 2005, three out of every four plates of rice eaten in Haiti came from the US." During this period, USAID invested heavily in Haiti, but this "charity" came not in the form of grants to develop Haiti's agricultural infrastructure, but in direct food aid, furthering Haiti's dependence on foreign assistance while also funneling money back to US agribusiness.
