These happens frequently, that's to have economic change and decide to change location. At times this decision becomes wrong within less than ten months to twelve months of such relocation.
What's your idea on relocation (definitely to more costly location) after a change in bank account or whichever way this economic change has happened?
People have been chasing better economic fortune for a long time. Obviously if you're super rich already you can pretty much go wherever you want and there is usually a way to pay your way in - either buying property or going through some sort of residency process if you want to have it as your main home. However, other people often try to emigrate because it means more money or a better standard of living. Places like America might pay higher than many parts of Europe for example, but you also have massive expenses like health insurance, medicine or medical expenditures which could potentially bankrupt you. Then there are people within Europe itself who live in poorer countries in the bloc and decide to use the freedom of movement to settle in a richer part of the bloc, but ultimately every country in the EU benefits from this arrangement eventually. The same is true in places like Asia, Africa and every other place in the world.
People don't really move because of money. Or they tell themselves that they do.
People walk into US with their eyes open because the number of the salary is so large that makes your brain stop working properly. And then slowly you realize that healthcare costs are insane, rent is insane. And somehow you're working more than you ever did at home but somehow feel like you're behind. That's a very certain kind of exhaustion. Something worse actually. Being quite technically fine but never being relaxed about it.
Rich people moving is an entirely different matter. I almost think it is a mistake to have it in the same conversation. They're not migrating. They're optimizing. Tax residency here, property there, passport from somewhere else. Regular people don't get to think that way. They're making irreversible decisions with incomplete information under the pressure of time, usually because staying was worse than the risk of going.
Humans are embarrassingly, deeply, wrong at predicting what will make them okay in the long run. You can model income, cost of living, career trajectory. You can't model if you're gonna feel at home somewhere. Some people are fine when they relocate. New place strips away old identity and they make something better. That happens. But other people are just there somewhere else.
We don't really know what we're optimising for when we move. We think it's economic.
