They could take that $240 billion dollars away from the rich, redistribute it to the needy all over the world, and once those “needy” spend it, they’ll have to come back for another $240 billion, which won’t be there the next time. Then, the needy and the rich will be equally poor and destitute and without a prayer. The rich could probably start over, but what incentives would there be for them, but the number of poor will either remain the same or grow bigger.
Poverty is not something that can ever be overcome by government programs, or by taking money from the well-off to give to the poor, or by just giving them handouts.
The rich just set up businesses selling beer to the "needy" and it all comes right back. :)
