Those “lifers” will quite often also just not be fit to work. Physically, sure, but they might be mentally fucked. I don’t mean full schizophrenia or something, just… broken people. Saw it all around me growing up, literally in my neighbors. People that were at some point just discarded. They can’t get a job and the longer they can’t get one, the less likely it is they’ll ever get one. They fall into alcoholism, health deteriorates… 20 years later the chances of them getting a job are slim to none because nobody would hire them. They just end up stuck, lost in a system that doesn’t care about them.
