Always amusing that lowering the percentage of natives in a culture is an improvement, "enrichment", "vibrancy", and so on, but only in one particular kind of direction...

And interestingly, the people who utter this ideology are usually from the natives - because fundamentally it's a type of narcissism - a kind of "I'll show you" or "I like you being hurt" that feels pleasurable or gives a sense of superiority.

Can't imagine this ever being tolerated within China and Russia though, perhaps that's why they're the current bogeymen.
