I spent my youth in Communist Czechoslovakia. The Communist propaganda used to say that capitalism was standing at the edge of a ditch (or whatever is the right English word for a very deep excavation), implying it was about to collapse (as Marx had expected).

The people would ask (when confident Big Brother was not watching): "Why is capitalism standing at the edge of the ditch?"

Then they would answer: "It is looking at socialism that fell in."

Note: The Communists always referred to the system as socialism rather than communism.
