After reading several autobiographies of people who lived in the USSR, I've started to think that material shortages are actually the deliberate goal of people who run communist countries. More succinctly, without material shortages, communist-inspired governments rapidly cease to exist.
If the People are not presently experiencing a material shortage, then they do not rely on authority figures to go about the daily business of feeding and policing themselves. Without regular contact between the People and the central authority personnel, it becomes impossible for the central authority personnel to supervise and grant/revoke permissions for them. Supervision and permission were the two components absolutely required for the government of the USSR to continue to exist--supervision allows for the early identification of threats to the government structure, and "permission" systems create excuses for the government to deploy the violent martial caste against threats to their supremacy.
(It is self-evident that people don't like living inside systems where they're constantly monitored and supervised; millions of people around the world work very hard to leave supervision-heavy countries for less-supervised ones. Also, children everywhere chafe against school, and prisoners chafe against prison.)
So I don't believe a truly centrally-planned, communist government will ever generate a useful material surplus (food, medicine, tools, etc.). If it did, the People who enjoyed the results of the surplus would immediately stop participating in the centrally planned processes mandated upon them by the planning committees.
Conversely, the first thing any centrally-planned government will do is organize itself in such a way that all important goods become scarce, so that it can guarantee regular contact points with citizens and set up a robust system of permission granting and revocation.
