Education is tricky. The wrong education can really stunt your economic competitiveness. I'm sure the Soviet world had plenty of classroom time devoted to the glory of Communism. Each classroom probably had a politruk available to help out.
Too many kids go to other universities and study similar things. It's fine to explore these ideas, but at the end of the day you've got to make someone happy or they won't pay you.
They also had really good maths and other useful things. They actually did what many in the West many wanted. Their education wasn't bad, learning wrong history isn't really that economically relevant.
But yeah, if the economy can't use those people its just not effective.
Learning wrong history can be economically relevant. So much of history is about learning patterns of human behavior. Patterns that often repeat. If you learn wrong or untrue history your understanding of and expectations for human behavior will be incorrect which will certainly cause economic issues.
Maybe if you are in top level government. But for 99% of workers it doesn't matter much.
Also, much of typical school history most people learn is incredibly shallow and the waste majority of people barley remember anything. Research show this pretty clearly. So teaching something wrong, is not gone matter much.
