That I got. Humans in the Preservation Alliance didn’t have to sign up for contract labor and get shipped off to mines or whatever for 80 to 90 percent of their lifespans. There was some strange system where they all got their food and shelter and education and medical for free, no matter what job they did. It had something to do with the giant colony ship that had brought them here, and a promise by the original crew to take care of everyone in perpetuity if they would just get on the damn thing and not die in the old colony. (It was complicated and when I watched their historical dramas, I tended to fast forward through the economics parts.) Whatever, the humans seemed to like it.
