All USAID showed was now the grift machine works--most of that aid money was getting kicked back to corrupt politicians to pay for campaigns. Other monies were being siphoned off in the corrupt nations that accepted the funds. Those NGOs advertising for more "migration" were doing on the US taxpayer's own dime! So I don't know if we can draw many conclusions from it other than it created some money velocity in various forms.

America's cost of living crisis is in large part due to the huge carrying cost of all that graft--it wasn't illegal, mind you, just unethical.
