It's annoying but justice and equality are mates, aren't they? Justice always wants to hang out with equality. And equality is a real pain in the ass. Seriously.
Preventing the poorest of the poor from selling their products while we sing the virtues of the free market, that's not charity: That's a justice issue. Holding children to ransom for the debts of their grandparents, that's not charity: That's a justice issue. Withholding life-saving medicines out of deference to the Office of Patents, well that's not charity. To me, that's a justice issue.
