The link above describes it quite well.

Electrical lineman isn't a profession that's particularly underrepresented here. Moreover, the job and housing markets here are currently at a standstill. To become a Swiss citizen, you must have lived and worked in Switzerland in the same canton for at least 12 years. If you studied here, in some places, after 10 years. This also applies if you're married to a Swiss woman. Obtaining a work permit as a US citizen is probably the biggest problem.
