> allow direct political control over the government agencies

Why would this be far fetched? Many civilized countries, including the U.S., have similar policies.

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.

Hows that working out for the US?

It is widely viewed as obviously corrupt, including in the U.S. What other 'civilized' countries do it?
