With permission I will take the liberty of intervening in the conversation, since I found the subject interesting.

The truth is that migration should be completely banned or, in its absence, highly regulated, it seems to me that if there were freedom of transit, what would happen is that the socialists, once their country was economically destroyed, would go to live capitalist countries and then they would destroy them. Remember that in today's world, most people are socialists even if they do not declare themselves as such. They go to an economically prosperous country, and once they are there, they begin to demand a welfare state. Finally, I believe that people from the West and East, we are both in religion, cultural, economically, politically and socially incompatible.
