> But if poor people want to read books and forget to return them, it doesn’t help to punish them. Sometimes we just have to accept that a certain percentage of society can’t or won’t do socially responsible things all the time.
As someone who isn't and didn't grow up poor, yet has yet to ever return a borrowed library book (which is why I stopped going to libraries decades ago), I find your conflation of "poor people" and "can't or won't do socially responsible things" to be quite telling -- about your attitudes with respect to poor people.
I suggest you re-evaluate your ideas about intersection of socio-economic status and social responsibility, as it seems that you're wildly off-base[0] there.
