I wouldn't want US salaries with US costs of living.
Also working for companies located in Ireland[0] or Switzerland you can have your US salary, it's just that the pool of jobs is limited.

Not sure about Ireland, but Switzerland used to be true, but now it is also far behind since 5+ years.
See, Google Zurich vs Seattle
