@rberger that's not really true though. Communism isn't about modulating scarcity. It's about directing resources and labour towards public good through public ownership of the means of production.
This is precisely how sharing abundance is achieved in practical terms.
@rberger it's also incorrect to characterize communism as a 19th century ideology as if the idea hasn't been evolving since that time. We have modern socialist countries today that are based on principles of Marxism-Leninism. The philosophy is very much alive today.
