I think it’s only a matter of time before China comes apart under the communists. Time, innovation and the desire for profit is relentless. You can always count on change and with today’s technologies, change happens faster.
I don’t think the younger Chinese are going to be as obedient as their ancestors. I wonder how much North Korea’s existence is dependent on the Chinese. A China undid would create a lot of interesting scenarios.like the breakup of the USSR. China could very well come apart in a similar way.
The downside now is that one child will now have to support two parents and four grandparents as they get too old to work. Ain't gonna happen.
Also, if war threatens to erupt, parents are NOT going to like the possibility of losing their only child on some battlefield.
As far as North Korea, I could see the Chinese going in and dealing with the situation by killing the men, and distributing the women among their own people.
