Lord Peter Bauer famously once said foreign aid is:
"taxing poor people in rich countries and passing it on to rich people in poor countries."
Using the IMF, the World Bank, and UN Economic funds are just funneling welfare for foreign elites. Besides, 15 Billion a year is what we spend on Aide, which is about the same as the NASA budget. Now while its only about 1% of the budget it is still quite a bit of money for something most Americans dont approve of. The only problem is, it makes us look cheap or selfish...and we are at a time where our image has taken a beating FWIW.
