Consider this as an example. USAIDS sends XYZ International Food Fund $100,000,000 monthly for Bumfuckistan. $90,000,000 gets taken off the top for 'administrative expenses'.
Food actually purchased = $10,000,000.
Is it a good investment to continue to send $100,000,000 monthly or, perhaps, fire all the grifters, build different relationships in BumFuckistan and send them $50,000,000 per month instead?
My guess is the people in Bumfuckistan would be happier with option 2.
50% annual reduction to the US taxpayer. Five times more food to the Bumfuckistanians.
