Emigration is difficult, and will become more so if people attempt it on a large scale. The unfortunate implication is that those who can scale the current entry barriers (working-age people with scarce and marketable skills, dual citizens, and so on) should do so before the barriers get higher. But only a tiny fraction of the population will be able to manage this.
Seriously there are tens of millions of us. Leaving is not realistic for most people.
