US development policy was built for a world that no longer exists. When the US Agency for International Development (USAID) was created in 1961, foreign aid was by far the most important flow of resources to developing countries. Today, aid is a relative sideshow. International migrants send roughly four times more money home to developing countries (close to $500 billion per year) than all donors disburse in global aid (roughly $130 billion per year). Remittances sent from the United States to Latin America and the Caribbean ($32 billion per year) are more than five times the combined US economic and military assistance to the same countries (less than $6 billion per year). Individuals earn much more in the United States than in their home countries, and they develop valuable skills through migration, often transmitting useful ideas and technologies back to their home countries.
