The United States Agency for International Development (USAID) shuffles taxpayer money all over the world...usually with no input from United States taxpayers as to where it goes, or why.
If you are a United States citizen, be aware that some of the money you earn goes someplace a politician decides needs the money more than you do.
Frequently even after the USAID money part is gone, the 'aid' part lives on, maybe providing benefits other than International Development.
Or maybe not. These sidewalk entrepeneurs in Bluefields show us how this 'aid' lives on...in what can perhaps be viewed as small examples of International Development: shoe repair on one side and chinese video copies on the other.
