No, they don't think that, and that's not why they're doing it. I used to think the globalists were so rabid about the mass immigration agenda for purely economic reasons, and it is partly why, but it's not the only reason. The fact is that European individualism has proven to be a stubbornly enduring cultural trait, and one that makes it very hard for neo-feudalism to take Hold in Western societies in the same way that it already has everywhere else. European culture and values make European people very difficult to control, and so European people need to be replaced.
