@MisuseCase @Alon @kentwillard I don't think that's true in general. It might be true if everyone were equally situated to be able to move, so everyone would optimize towards equally good situations. But in real life, some people simply cannot move for a variety of reason, so freedom to migrate often exacerbates inequalities. Those who were already relatively well-situated move to even better circumstance. Those who were poorly situated are left-behind in places and circumstances now much worse.
