The dangerous, isolated environment of space and a worker's reliance on their employer for a ride home creates conditions ripe for abuse. This mirrors the exploitation of migrant fishing workers whose passports are confiscated, trapping them at sea for years in unsafe conditions.
Thinking about societal problems like crime in a resource-scarce space habitat forces consideration of radical alternatives to impractical solutions like prisons. This exercise can yield innovative strategies, like non-carceral justice systems, that could then be adapted and applied to improve communities on Earth.
Jamestown nearly collapsed because its upper-class colonists lacked survival skills and were pressured by financiers to find gold rather than build a sustainable habitat. A Mars colony could repeat this error by sending unskilled individuals and prioritizing resource mining over establishing self-sufficiency.
Lower Martian gravity would lead to weaker bones and muscles in children, making them too fragile for Earth's gravity. Furthermore, their immune systems would develop without Earth's microbial diversity, leaving them vulnerable to common microbes upon return, effectively making a trip to Earth a potential death sentence.
