Foreign aid is never intended to help the people of a nation. It's used by high-income democratic nations to support autocratic policies and resource extraction.

I doubt very much of that 793M makes it to any of the people pulling these scams. It's typically used as legal bribes for the governments of those countries, who distributed it to all their cronies at the top, in order to maintain power and sell national resources to the US/EU and others at very low prices.

The Dictators Handbook by Mesquita and Smith go into more details on how this works.
