I know a few who did that, worked 3 years and went back with a healthy savings.
The one time I went to the US I nearly had a panic attack, so I can't really imagine living there or dragging my family there, but then you look at the money and it sure looks worth dragging yourself through hell for.

I guess if you have psychological issues that make travel difficult or feel like "dragging yourself through hell", as you put it, then maybe just stay at home.
Another option is to work remote. You'll get paid less for being in an Asian time-zone, but you might still earn more than a local company would pay you.
A third option, which is the one I'm currently pursuing (from east Asia), is taking your skills directly to the market as an entrepreneur.
