Every State has the obligation to look after its own citizens. Otherwise, we should organize into a state that will as no other state will look after us. Can I go to Brazil or Russia and say, hey Russia, hey Brazil, you know, I'm neither Russian nor Brazilian and I didn't contribute anything to your country nor my did my ancestors, but I'd like some of your pie.
Also, we can't cry "wages have been stagnant since the 70s" and also want to continue ex-patriating jobs and ability to command better pay.
