You can expect 25%-50% the salary, with a cost-of-living similar to the SF Bay Area throughout the entire country. Relatively little jobs, a lot of legacy tech stacks, and these days a lot of stuff is outsourced to American SaaS platforms. High taxes, but they cover next to nothing for the average person.

Go to Eastern Europe, Switzerland, Scandinavia, maybe Italy or Greece.

For example?

Yep. Like the US.
