I'd probably only do it for survival reasons or temporarily for learning. I've considered moving a lot in my life (specially fooled by brain drain Western propaganda), but the whole process is too costly and risky, and doesn't help make my country a better place.

If I get the conditions to afford moving elsewhere, I would also likely have the conditions to live a comfortable life or try to make a change here.

But it's always good to learn some Chinese and Spanish as backup ;)
