That's simply not correct, US businesses in the so-called "Third World" are very profitable. What is not profitable is US aid which is transferred to Swiss Bank accounts.
Ford's business in Brazil, for example, is very profitable and apart from Venezuela and a few basket cases, you can do very profitable business in Latin / Central America.
Instead of aid lets allow businesses to invest and get out of their way. Seems to me our governmnet allows aid to go to the wrong place and no one seems to be held into account.
The beast must be starved of funds...
