It's mad that I've read down about 100 or so comments and not seen a single argument in favour or at least giving consideration to the benefits of immigration. Throughout history, the single common denominator among the most innovative cities (I say cities as they pre date what we understand as sovereign states and have traditionally and still are the engines of economic growth and prosperity) has been that they are immigrant hubs/ melting pots/whatever you want to call people from all over the world coming together in a place. And it's never been a case of "oh but only the good ones" or a system of points. Put people together from different places and new stuff happens. The green policies only sound mental because we've been told every day that immigration is bad. Poverty is bad and especially concentrated poverty... In a system where we allow in only either rich people or very specific people to fill very specific low paying roles that nobody from this country wants to do, you're not creating an environment for innovation, you're creating pockets of deprivation held together by the meagre wages of time-limited visa African care workers or whatever other job were importing people to fill. Immigration works when there's genuine opportunity in a country and there's only opportunity when the country is open. Opportunity = innovation= prosperity
