I lived in Switzerland, paid 12% taxes and 5% for AHV (public pension fund, you don't get this money back), lived in a 100sqm (1000sqf) flat for 1800 chf a month, 25 min to zurich by train but only a 15min bike ride to work, ~110k salary
You can get a work visa if a Swiss company wants to hire you for a special skill or expertise you have. The easier way is probably to start working for a Swiss company in the US and then let you relocate to Switzerland still working for that company.
