I think Switzerland is the best place to live in the world!
Just got back from there. Visited one of my friends. Income is high, 2-3 times higher than the US. $5-6K/per month is minimum. $10-20K/month is quite common. Income tax is very low,13% in the canton I visited. Rent is low, owning a place is not cheap though. Supermaket price is very reasonable and on top of everything-- Switzerland is one of the most beautiful places in the world no doubt!
