Something I've always wondered is, assuming a hypothetical perfect communist system, what would the standard of living look like? I've seen people try to make arguments based on taking the GDP/GNP then dividing it by the population, which works out at about $70k per person. But then they're picturing that within a current system of artificially constrained housing supply, for profit healthcare/education, and 10x price markups. Assuming a perfectly efficient system in which the only costs are resources + time, and 90% of society's labor isn't going to sustaining completely useless overhead, what does the average lifestyle look like?
