If "understanding the poor" is your goal, you'd do well to dispense with the condescending generalizations.
But, mostly this was just me refuting your claim that I don't understand what it's like to be poor (and desperate). I could go on, in ways that don't have anything to do with organized crime, but I have to go now. It's really infuriating being told by someone that doesn't understand your experience that you don't understand your own experience.
Although now she owes him child support every month. But any payment she makes goes right back to her, to be deducted against what he owes her.[1]
Friends and family have given him a place to live where he acts as a stay-at-home dad, since for now working is useless (and the child require 24/7 monitoring by adults). If friends and family were to give him the money to pay off the debt, it would just give the money to his ex, and there is no guarantee that she would then start paying her side of the debt.[1] I guess she would then be the one unable to get a driver's license and go to work and pay child support, which is "justice" only in a weird warped sense of the word in that they each have suffered the same kind of injustice, and doesn't really help the kids.
[1] The ideal situation is to just have both debts neutralize each other and disappear, but it's not clear that this would be binding even if you could get the two angry ex'es to agree to it -- parents have signed off on child support in the past only to have the courts put it in place anyway, since the kids couldn't sign it away.
