But it is the same principle inside a big country like US which is really vast geographically. Look at Europe. Properties in Eastern Europe are still a lot cheaper yet most university educated young people are migrating from east to west. So obviously they value the economic and career opportunities in those big metros in Western Europe and even though flats there cost 2x or 3x they still go. Just because you can buy cheap house in Mississippi is not going to cause young doctors, engineers, lawyers, other professionals and graduates from top schools to start migrating there. It's just not worth it for them, they are looking at their long term career prospects and can do the math.
