Perhaps to westerners and perhaps to you. To other people, that is not necessarily always the case. For example, my family has lived in the city where I reside for less than 100 years. This is my home but it's not my ancestral home. If I were from India, if my family had a connection to an area that went back hundreds or possibly even thousands of years to a region, if I could live similarly to how I live here on the kind of salary the job pays there, I wouldn't be in a big rush to leave either. Would I leave this area to make 10x what I earn now? Probably. If I left for 5-10 years, I could come back and retire. Is there any pressing or burning need? No. Not at all. Even though I could be persuaded to go somewhere else, there are still limits to where I'd go. I wouldn't move to North Korea, even to make 20x my current income. I wouldn't move to any of the former Soviet republics. I wouldn't move to most of Central or South America. I wouldn't move to most of Africa. I get it, for you, most of these concerns are trivial but that's simply not the case for a lot of people.
