I don't think that universally true. I work for G in Munich, and salaries post cost of living are competitive with the Bay Area (maybe 10%-20% off, but OTOH consider quality of life). From what I can tell, Zurich beats the Bay Area.
Not really. Out of all FAANGs there's just Google in Zurich with a significant presence. They pay well above almost all other swiss and european companies, but are not really the top paying employer in the Bay anymore.
Not being able to job hop among FAANGs is a big risk to your compensation here in the long term and will make you eventually lose out to Bay Area, even despite lower taxes.

Yes, with the similar salaries and a 1:1 exchange rate between CHF and USD and the only tax is the Cantonal tax of 13% vs 50% for Bay Area, it makes Zurich way far ahead.
The offices in Zug down the street get only 7% tax.
And healthcare is free, but its a negligible concern at these compensation ranges. It just shows how the American arguments fall apart, since most of them are based on "how much Europeans must have to be taxed"
If you like having a 40+ min commute instead of a few minutes of walking/biking for a few thousands of tax savings a year. Some people don't. Generally the richer you are the more you get to value your own time.
