But it keeps the left alive. Without diversity, the left is a bunch of corpulent unions protecting their pensions while the young people look at brochures of London and Los Angeles and finish their fourth degree. Without it, the left eventually dries up, blows away in the wind and dies after running a few protests against austerity and then has to implement it anyway.
Diversity isn’t a moral principle. It’s oxygen for a dead movement. It’s the only way that the left can stay alive long enough to fulfill the accidental mission of every parasite by killing its host. It’s the numbers game and as long as the left can cobble together these coalitions built on the backs of immigrants and tied together with community associations and piles of free stuff, then it can go on squatting on a society, dipping its proboscis in the sweet nectar of wealth and power, and then when the nectar runs out, switching to sipping its blood.
The left needs immigration to run its numbers game. It needs immigration to survive. It needs immigration to force further change on societies that would be static if left to their own devices. It needs immigration to provide it with a permanently disadvantaged working class from an infinite supply of billions. It needs to make its own failed society fail in new ways by injecting other failed societies into it.
Play the diversity of numbers and the kids stop dreaming of London and LA and start hanging out at clubs where diversity seems to make life more exciting. The declining native upper class and the immigrant working class shake hands over the bodies of the native working class and the whole broken train rumbles forward into the night.
