People are born everyday on Earth into far worse circumstances then "we live in this spaceship". The spaceship by comparison is paradise (though it's also worth noting you thought the point wasn't quite strong enough if you didn't start adding modifiers: no democracy, the government must be authoritarian...)

Exactly. If growing up on a spaceship was all you ever knew, it wouldn't seem like a problem. It only seems like a problem to people who grew up with a lot of choices on Earth. Most people on our planet don't have a lot of choices in how they live their life.
