You think every person only thinks of their own job and no one dreams of anything bigger from humanity’s perspective? I’m never going to be in some kind of space colony but do I want to see them happen? You betcha.

Yes, the vast majority of people care about their jobs first rather than a theoretical future where mostly rich people colonize space. It's much easier to imagine yourself becoming poor than living in Mars.
