Answer:
Communism on paper is good but in practice.. meh not really.
Explanation:
The Soviet Union, Vietnam, China, and Cuba advocate Capitalist policies because they can make more money off of that. True Communism, such as Marxism would be unrealistically hard to pull off in actual society. This means no one should move up the social ladder as that would go against the ideals of Communism. People are naturally ambitious, which would be a problem with the economics of true Communism.
The civil service system is much better than the alternative, which was Patronage. as implemented by the Hoover Commission. Civil service sets employment competence standards for hiring and makes working a permanent career, not just until the next election. it was so outstandingly successful, that virtually every state and community government follows it to large extent.
I hope this helps :)
