Everyone who has to live in it hates Brasilia. You can force people to live there because it's a powerful capital city, but it's still awful.
Sorry to break it, but mostly people do like here (I know, because I don't - I'd much rather life at some smaller city).
Some come from a coastal area, and will keep complaining about the lack of a sea their entire life, and they are loud. If you are just listening around, you'll get a very biased sample.
Are you sure? I've mostly heard complaints about it.
A national capital is an exception, not the rule.
Wait until its main industry moves or goes into crisis.
Of all places its one has smallest chances to move or go into crisis.
sure
but it certainly did move there. So it's not like it's 0% chances long term.
