I used to go to Brasilia 3-4 times a month for work. If you got on a Tuesday morning flight you could rub shoulders with congressmen, top-level cabinet ministers, supreme court justices and so on. Many would easily engage you in conversation, too; maybe because I didn't open with political subjects and mainly complained about having to go to Brasilia.

The first problem with Brasilia is that it's horribly located. We did avoid the Stockholm fate of having our historical cities razed, but moved the seat of power to the middle of nowhere. I know that overpaid lower-ranking bureaucrats have houses in the outer rings, near the lakes; but no one who has an actual choice lives in Brasilia. I don't know if it fully qualifies as a city. If the capital ever moves, it will be a ghost town in three weeks and start crumbling (bad architecture and bad construction) within the year.
