I read that the ChiCom's one-child policy resulted in the murder or abandonment of female children because males were much more valued in that culture. Now, there is a tremendous surplus of extremely depressed males who are committing suicide rather than spend their lives alone in forced labor at factories and such. The remaining females are suddenly valued. The ChiComs don't seem to learn.
I was born in 1947, and remember hearing about the bread lines in the U.S.S.R. I remember seeing Khruschev on TV when he came to the U.S., and how he said communism would bury this country. He got ticked because they wouldn't let him go to Disneyland.
A lot of people don't know that Great Britain, after WWII ended, continued the rationing of food until 1954. And despite the fact that the U.K. depended so much on overseas food imports during WWI, they did nothing to alleviate that before WWII rolled around. They were still reliant on imports.
During WWII, Stalin ordered the end of production of farm machinery/equipment, and required factories to produce nothing but equipment for the war. Farmers were at a loss to successfully grow the grain and vegetables needed to feed the nation. That's why so many Russians starved to death.
