That's not the same thing and you know it. If you were resentful at having been born into a sealed can the side of a large office building, with a meager lifestyle and-- by necessity-- an authoritarian government that chooses your occupation, spouse, etc., and you heard about the paradise of Earth, you know perfectly well your anger wouldn't be assuaged by "no one born there has a say in their circumstances either".

[XorNot]

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.
