I'm conflicted on this issue. First off, I'm an economic migrant. I also had the privilege of being able to move without a skilled work visa. I'm all for freedom of movement, I think that borders are an artificial construct that cause more harm than good. But we need to balance that with the fact that unchecked migration can cause excessive strain on infrastructure, cause cultural clashes, and potentially cause lowered quality of life for residents of the country being emigrated to, caused by residents being priced out of the market by workers willing to work for near-nothing because it's still better than the wages back at home. New Zealand has suffered a lot of these problems. Auckland in particular suffering from the strain of high levels of immigration on its infrastructure. There simply isn't enough housing for all the people. You end up with people sharing rooms and packing out apartments like a slum. I've heard of people fitting 4 people to a room using bunk beds. So you've got 12 people in a 3 bedroom apartment. The apartments aren't designed for this kind of population density, and it pushes out people who want a decent quality of life and a room to themselves, as they're priced out by people willing to share 4 to a room. High immigration with a low barrier has also caused deflation of wages. Some Indian workers come to NZ and work for under minimum wage, either by employers requiring repayment of wages or underpaying wages (which is illegal), or by working for gig-economy services like Uber (which is legal). For a lot of immigrants, working for $5 an hour and sharing an apartment with 10 other people is still a better quality of life than back home, but it drags down the quality of life for other Kiwis. I think part of the problem is that it's possible for people to move anywhere in the world within 30 hours. Instead of migrating to a neighbouring country that has a slightly better economy to yours, if the world had total freedom of movement, everyone would flock to the most prosperous nations, causing the middle nations to miss out completely. How many undocumented migrants to Europe want to stay in Italy or Greece? They all want to get to Germany, France, or the UK. I think that maybe the best solution for the world would be freedom of movement between bordering nations. Most bordering nations will have similar economies, running as a continuum across the globe, and will also have similar cultures (as I said, borders are an artificial construct that cut through ethnic and cultural lines). The USA-Mexico border is an exception here, with a massive economic disparity between the two countries. I think that it's wrong that just because you were born on one side of a line you're condemned to a lower quality of life than your neighbours, earning a fraction of the same income for the same work.
