Where independent unions are banned.
Basically when China and Russia gave up on socialism, they created a version of capitalism in the image of what they imagined capitalism to be; not the kind of liberal society you find in advanced Western democracies with their regulated market economies and worker's rights guarantees.
Indigenous means "originating where it is found", or "naturally occurring in a particular place". It can be used referring to individuals, groups of people, flora, fauna, minerals -- pretty much anything. It shares many of the same dictionary definitions as "native".
The word usage problem is using "indigenous" for an artificial, mobile invention, which is a bit unusual. You wouldn't say "indigenous airplane" because it's not something naturally found in a place or confined to a place. That would be an unusual usage, but people would understand what you meant -- you'd mean "domestically produced".
Depends on the nature of the "disability". We judge disability by how well people function in society as it currently exists. It doesn't mean that they can't function in an artificially engineered society (e.g. one consisting of autistic spectrum people).
... or you may find out the people best adapted to a Mars mission are people with characteristics which are seen as socially debilitating.
Well, it depends on what your research objectives are. ISS is in some ways a better model, in some ways a worse one. It's better in that it's in space with microgravity, but ISS crew members rotate in and out. Even if individuals spend the equivalent time of a Mars mission on the ISS there will be new faces, a constantly changing research workload, and the ever-changing panorama of the Earth below.
So it's not a very accurate model of the social dynamics of a Mars mission where people are cooped up in a can with the same faces, same scenery, and nothing but busy-work to keep them occupied. Let's say we lick the radiation and microgravity problems; the question then becomes what kind of people can successfully negotiate the trip to Mars, arriving ready to work successfully there?
Well, you don't like to see movies that cater just to women. Most women don't like to see movies that cater just to guys.
Doesn't take a genius to figure that out.
