For good companies; there are _quite_ a few companies that underpay and not as many interesting job opportunities. Let's just say "at least 2x~2.5" and move on.

Also, even if you did not mention it, UK is a bit of a special case (English-speaking countries that has thus been attracting quite a lot of international talent (and companies) at least until recently), I wouldn't put it in the same bucket as EU countries.
