I did retirement home training and used to think it was a sweet job. Then I got in the business and underestimated how demoralizing it was as they give you the easy elders in training while the others make you, or at least me, really think of the fact the job just amounts to an unkarmic freebie.
That is exactly what it’s for, and it prevents a lot of worse problems just by existing. It significantly reduces crime rates by allowing people who otherwise couldn’t earn income, and provides a way for ex-cons to successfully reintegrate into society and not relapse, as well as providing low/no skill labor. It gives some a sense of purpose - retirees who physically can’t do any other work for example and need something to do.
It is literally there to give people jobs and its a good thing.
