I wouldn't necessarily say that the U.S. federal administration is in a super healthy state right now. The Swedish administration model has its roots in the seventeenth century and is thus older than the Swedish democracy. It has generally worked well, Swedish authorities are trusted in a high degree in general and the authorities can work independently and professionally without too much direct meddling from the government.

The democracy in the U.S. is in a far healthier state than most European nations where there aren't any caps on the tenure of government leaders.

Hungary's Orban had been in power for 16 years and if he'd won the election it would've been impossible to ever remove him.
