All this discussion makes me wonder - is there any country an immigrant can move to, and better their lives as well as the locals' life/economy? Assuming the immigrant makes every effort to integrate (learning the language, respecting local people/customs etc). It seems the world is turning hostile to immigration in general - or maybe it is just the impression I get from the media? I don't know for sure.
Not really anymore. All the good ponds have all been fished out by now.
Housing is in short supply in every livable city in the western world and the job market is tight right now, so if you move there now, you're one, increasing labor competition for the locals, and two, rising housing prices for the locals. THe only locals happy with this arrangement are the corporation hiring you and the landlord taking your money.
The world has min-maxed itself into oblivion that it's already reached saturation point. We're way passed the balance point, everything is fucked, there's no magic place on the planet where things are nice for everyone.
