A commentator wrote, "Buying a homeless man a sandwich for two dollars is a direct investment of resources. Appropriating twenty billion dollars to feed a sandwich to every homeless man in America will feed sandwiches to a small percentage of the homeless at a cost of four thousand dollars a sandwich."

Taking the minimum possible OP number of 'tens of millions', ie 20 million, that gives just $110 per child, less exes, so they each get a bowl of rice...and the mindless masses will feel righteous as another money mountain disappears into numbered accounts.

But maybe I'm wrong and the UN can be trusted with that kind of money.
