That's a fair observation. I'm curious though, do you have any ideas to improve the situation? What would you do if you were responsible for 1.5B people and were facing a situation where the labor force participation drops by half over the next ten years and continues to drop every year since? Will you be able to arrange for the population to be able to be fed, clothed, housed, and given medical care?
It's not possible to "magically" create several hundred million young people, communism or no, to "fix it". So what do you do?
