As a side note, Syfy channel's Expanse show takes place in that kind of an environment. There are "belters" whole generations who have worked mining asteroids. There is the "Mars" faction, descendants of Mars colonizers, and of course Earth. They end up conflict + some added human interpersonal drama mixed in etc, etc.

As a show not top notch, but not bad either. It was interesting that it was exploring the Solar system as opposed the traditional space sci fi plot with aliens invading or having to go through wormholes to outer rims of the universe.
