We have our own model and it works, but is being sorely tested by South of The Border horde of the 1980s and 90s. We get some trickle from the Pacific, but they come with skills, language (with accent of course) and with hopes of creating wealth beyond their dreams and contribute to the masses. I'm not sure those from North Atlantic would even want to settle here anymore since we don't have mandatory public services that they universally consider a "human right".
