Did communist party built at least single successful country in Africa?

It's like saying that Nazis helped a common man in Germany. And they did! Life for a common German man definitely got better in mid-late 1930s. But at a cost..

Regarding USSR, that help to far away countries was one of the reason why it fell. Life in USSR was shitty (maybe not Africa-shitty, but still). And people were unhappy that resources are sent away instead of improving their lives. There were plenty of jokes that there's no food or merchandise since some revolutioner dude in South America or Africa eats or wears them.
