I don't agree with all of Matt's predictions here, but at around 1h11m in he talks about how fertility rates among whites really aren't that bad in America, while they're plummeting throughout the Global South. In fact, fertility rates have gone off a cliff for non-whites throughout the world (including in the West), and they're dropping even faster than they ever did in America or even in Europe.
Whatever you blame for low fertility rates (urbanization, industrialization, liberalism, feminism, a financialized economy, individualism, materialism, etc.), whites were affected first. I believe what we're seeing now is a more complex version of the declines in fertility that had cyclically plagued past civilizations. The way I see it, whites were the first to enter this dark tunnel of low fertility. I believe we may soon see light at the end of that tunnel at a time when other peoples are just entering the tunnel. Naturally, we will be the first to emerge out of this end of the cycle.
As Matt points out, the sources of immigration will be drying up in the coming decades. I'd also add that continued automation, roboticization, and the proliferation of A.I. will likely cause a job crunch, resulting in a fair number of non-whites in Western countries returning to their ancestral homelands in seek of the type of jobs that will desperately need to be filled in socieities that will, by then, be rapidly aging. With these demographic variables shifting, and with white identity emerging across the West, I am confident that whites will be able to determine their own destiny, whether we end up in countless enclaves or are able to direct some sort of quasi-fascist managerial state that implicitly or explicitly gives preference to the interests of it's white population.
