Workers are weird. No matter where you are in the galaxy, there is an unlimited supply of workers that will show up the moment you build housing for them. There is no discussion of ever paying one’s workers - all they want is food and water (and some coffee if you’re feeling generous). If you stop feeding them, they go into hibernation, and when you bring more food they immediately pick up where they left off without resenting you the least bit for letting them starve.
Treating workers as individuals might make the game more interesting and open up new playstyles. Players could compete for the best workers through good work conditions and compensation, or just squeeze them for all they’re worth. You could even create ways to upgrade workers into Experts or upgrade pioneers into settlers.
Workers feel so alien that it’s hard to empathize with them, and that makes the whole economy less meaningful. I feel like I’m roleplaying as Ebenezer Scrooge.
