Just a step on the inevitable road to one world polity. We should really be working out a roadmap to a world where everyone is a citizen of a worldstate with freedom to move, travel and trade freely regardless of where they were born. Basic rights should be protected everywhere by global enforcement, Borders should be administrative niceties and people should be free to migrate to areas which reflect their social and religious preferences in a global freemarket of societies where the most beneficial policies result in people voting with their feet.
I’ve always thought the same thing and yet looking at the state of the big federations right now, Russia and the USA today, it is worth considering if deeper integration has its own potential pitfalls.
