Oh I read that too, and again you're making an additional logical leap with your idea that isn't always true.
Weird, because I feel like you're jumping past the point because it isn't technically spelled out in the USC that someone will arrest you if you don't make enough money.
If someone sues you civilly, you receive no notice of it, and then they arrest you and put you in prison, I get that there are intervening steps, but it's literally the same result.
I understand that sometimes people get notice and might have the ability to show up in court and they do, but the OP's point isn't that every poor person is in jail. The point is that they're put there when rich people aren't.
That the OP can't cite a PL that says being poor is illegal doesn't exculpate society from putting them in prison because they're poor. I'm sorry that it's insidious and underhanded, but it is literally happening.
I also don't think the OP is trying to change anyone's mind. I'm not either. I don't think the people who criminalize being poor are worth the effort. The point of these types of posts isn't to change minds. It's to overcome the apathy of the majority of people who already know it's wrong to do this and use that majority to forcibly remove power from those people whose minds you want to change.
