What kind of control over ships do the stations have? Like are there no privately owned ships or something?

Their are privately owned ships. The Stations have there own ships used for transporting people/supplies on and off Station. But corporations, colonies, and private citizens can have there own ships. Space is the final frontier, so there are a lot of people exploring, or who have ships of there own that they use for travel, and typically get hired by others to transport cargo. So there are merchants, pirates, travelers, and so on.

I love this idea!
If I get my creative juices back up and flowing, I'll probably join.

However, I would like to point something out-
A total of 21 million people can be saved on these 7 space stations.
You said 80 million people were being left behind to die.
Current global population is over 7 billion- we reached the mark at 2011/2012, and that was 4 or 5 years ago. What happened to the billions of other people? A World War 5 might be devastating, but not enough to decimate 80% or 90% of the population- that's genocide, not war. War isn't that destructive.

Natural disasters, war, famine, nuclear bombs, and so on. The world was on its last legs, people were not doing so well. I'll change the 80 million to 11 billion.  :D
