Land, energy infrastructure, mineral deposits, grid capacity, etc.
Who gets to live in the nice parts of the world? Who has a national park as a neighbour? Who gets to be ravaged by hurricanes every year? Who gets to have more energy production closer to then? Who will own the land that has the finite resources that are used to create abundance? Where will people with the most power live?
There are so many reasons beyond production why certain areas fare better than others inherently, I have not seen any answer to this apart from that all rich people will just fold and we will all be moved into soviet skyscrapers which I find improbable.
