US is the outlier. Canadian tech salaries are much higher than European, and when working remotely for a US company the compensation overlaps the US salary bands very substantially.

However the ceiling in the US is so much higher that it still makes sense for many to tolerate the chaos and uncertainty of moving here for work.

Exactly. It's an adventure of sorts, and if you're in tech you're in a small percentage of the world population that can gain some degree of wealth. A lot in some cases. It's a risk that's attracted people to the US for centuries. Many people, and I'll admit to being one of them, hope to get some savings, and then move to one of those low wage European countries with a better quality of life!
