> Personally I'm waiting for engineering salaries in the non-US to catch up to the US because it'll make it easier for me to leave the US if I choose to do so but it doesn't look like it's happened yet.

Let me chime in to say that salary isn't everything in life, or the key to live a good, fulfilling life. I'd even argue that socialized healthcare and worker's rights, ensured in numerous European countries, do far more to achieve good life than, say, an absurdly high salary.
