Because, frankly, Britain owes the impoverished countries we give aid to more money than we will ever even come close to repaying? Most of them are impoverished, at least in part, because of how extensively the British Empire exploited the world in order to become "Great". It's really that simple. And we give them a pittance.

It's essentially like robbing a man blind, burning his home and business to the ground, then giving him £2 when you pass him slumped at the side of the street a decade later and being pissed off when he spends it on drugs.
