As a DINK household where both are tech workers - you have hit the nail on the head. We both can get visas to jist about anywhere in the western world with little to no difficulty, so for us it comes down to quality of life and salary. Sadly European salaries are so far depressed from our “normal” ( I make no illusion, we are well paid) take-home salary, that considering relocating across the globe is not currently a worthwhile headache.
