Food banks depend on the largesse of the people that can afford to buy food though, which, well... if the only people remaining in that group are the ones gleefully saying how they're going to create a permanent underclass...

I've done social-work–adjacent stuff and I know a lot of NGOs in my country are quite strained (of course, probably housing more than food, so I don't disagree that might be more of a concern). I imagine it wouldn't be too different in America.
