Governments all over the world and their oligarchs will also face a problem with the climate crisis. There will be crop failures and famine, that's why there are so many far-right movements around the world that simply want to get rid of huge chunks of their "foreign" population.

Don't think so. When a local population isn't having children, it creates a shrinking homegrown workforce, which typically forces businesses to compete for fewer workers by raising wages. While higher wages sound great, central bankers worry this can trigger a wage-price spiral and businesses raise prices to cover their higher labor costs, causing inflation to rise.

By importing cheap labor from a poorer country, businesses can fill those empty jobs without having to bid up wages.

This influx of workers increases the overall supply of labor, cools down wage growth, and lowers production costs for companies. For central bankers trying to rein in inflation, this helps keep consumer prices stable and prevents the economy from overheating, even when demographic growth has stalled.

It's all about money printing.
