For a bit of time I worked offshore for a company in the US. That was pure cost cutting, I was making probably around 5x-10x less than someone with similar skills in the US.

After a while I landed a job that required me to migrate to a different country. I actually make more here than the average salary for a local engineer.

I don't know many machinists that are hired from halfway across the globe, relocation costs included, to make more than the average machinist in the destination country.
