Welfare for the poor has as much cantillion effect as welfare for the rich. In both cases, it uses fiat money creation to leech from the productive and unbinds cultural regulation of ethics.
Not quite. Canillon effects are strongest at the point where money enters the economy. In our system, new money enters through the banking sector. If there were no taxes and all government spending was freshly created money, then you'd be right. Welfare spending still has Cantillon effects, but they aren't as strong, because they're a few steps down the chain of events.
