Elon Musk's plan for Martian indentured servitude for those who can't afford to travel there is typical of the profound failings of capitalism in terms of planning and a great example of why I hate "free market space colonization" in science fiction media. #WiP #TTRPG
You see, he doesn't imagine or question "what comes next", or if he does, he doesn't talk about it because he knows that people would immediately crucify him.
Mars, or any planet that isn't terraformed, is completely or nearly completely reliant on imports to survive.
Food, water, medical supplies, replacement parts, construction materials, the lot. So what happens when an indentured labourer pays off their indenture? Where do they go? What can they do? They're trapped on a world where they have no power and their access to resources is...
...dictated to them by the powers who have the wealth to import those resources. They aren't going to get a slice of land. They can't homestead. And do you honestly think that Lord of Mars, Elon Musk is going to hand out those resources? Hell no! No capitalist would.
Why? Because there's no profit in it. At best, they might extend a huge loan to let them set up in a fashion that keeps the now "free" labourer beholden to them. And it's not like the labourer can leave either. Trips home aren't going to be free, and that's a feature, not a bug.
