Not long ago, my son asked for a bit of brainstorming on what I could see as developing social issues for a science fiction piece he was working on (his science fiction is in game format, which entails, in his case, about two novels' worth of writing, for background, color text, etc). I said I thought the way thingfs were going, institutionalized slavery looked like a real thing to be concerned about.
This is one of the reasons why.
