Mass immigration tends to work politically like a doomsday machine, a juggernaut progressively cutting down the ability to call off immigration due to diminishing marginal returns. As a Western nation imports more individuals from the self-destructive parts of the world, the demands to admit their extended family members grow as well. (…)
To paraphrase Christopher Caldwell’s 2009 aperçu:
“One moves swiftly and imperceptibly from a world in which immigration can’t be ended because its beneficiaries are too weak to a world in which it can’t be ended because its beneficiaries are too strong.”
