Yes, they did spread the system all over the place, and people fail to realize their first attempt to do this was back in 1917 - 1918, at the end of the first world war, when they tried to overthrow all of the western countries. They succeeded with Russia. From then through now, their efforts have not ended, and country after country has fallen. I cannot think of a single example where a communist nation has been able to feed themselves. Maybe Cuba, or Vietnam, but certainly not many . Cuba remains an impoverished shithole even if they do have enough to eat. Vietnam now begs for western investment. The pattern is always the same. Communists come to power, and poverty rapidly follows. The good news is in those countries where the communists have been removed, real wealth makes a steady, if not entirely rapid, comeback. The average Russian today actually enjoys a standard of living approaching that of the average American. Their real incomes have increased 10+ fold over the last 25 years, and are still growing.
