Ummm... maybe because the Africans will ruin it?
yeah, they might do like the Japanese and Germans did after WWII, when the U.S. could have used all of those BILLIONS to do something else in our country. Who knows, we probably wouldn't even have to worry about old europe getting in the way and supporting terrorists against the interest of the U.S.
"... because the Africans will ruin it."
Precisely. We need to stop calling these funds 'loans', for they were never intended to be repaid. Money being sent to Africa is Charity for people without the inner capacity to provide for themselves.
