After finishing #ForAllMankind on Apple TV+ I am convinced ...
(spoilers)
... that this is a prequel to The Expanse, and the colonists left on Mars are the ancestors of the belters.
@MattMerk don't think so.
Belters were shipped up-well from Earth as indentured slaves by corporations. People choose Mars to contribute to a better (far) future.
Not sure a long time dusty would get along with a short term thinking rock hopper
