I am not highly intellectual like you, but I think the main reason you'd be drawn to a country that "has a better culture", is their economical success, so there will always be this issue of countries successful economically being the "better culture". In the example of tribe a/b, tribe a is weak, you wanna be with tribe b, tribe b require you to be strong before you join. Strength today is in term of labor output, if you are highly qualified (not only highly intellectual sadly) you will be invited by tribe b. Also why would a country invite on the basis of you agreeing with them, they are full of people agreeing with them, they want people who are useful to them. Also if someone who lives in a "better" country, yes it was given to them by their fathers and grandfathers, that's a privilege that they got without doing any work (it take some work to maintain tho), but they have no obligation to give it to you, or share it with you, you can't argue for it with "but I am sad cuz I don't have it too :(". If it is basic needs yeah, but arguing for luxuries I am not with you. On an individual level, you do not hand people around you that are less fortunate than you in your society some of the privilege you were born with to the point that you made them your equal (economically).
