well that's a different 'kind' of corruption
corruption you have to GIVE to get stuff done
vs corruption with loophole for RECEIVING money
(I'd rather have the latter )
The two aren't really separate, because the grifters who are on the receiving end also often end up being ones "donating" to the corrupt politicians who select their organizations to receive money.
The NGOs find ways to route the received money back to the politicians in the form of campaign donations, or having a politician's friend/relative being an executive at the NGO.
The NGOs also subcontract to other NGOs, who take their cut, and eventually just a trickle winds up going to the purpose of giving money to the NGO.
