A defining feature of communism is its failure to manifest. For the record, I do support many socialist policies, it's just fun to rain on the commie circle jerk.
Ah yes, thousands of years of the best and brightest minds trying to figure out what human nature really is and you’ve figured it out! Congratulations! What journal did you publish your findings in? What did you base your conclusions on, vibes?
Men are not good enough for Communism, but are they good enough for Capitalism? If all men were good-hearted, kind, and just, they would never exploit one another, although possessing the means of doing so. With such men the private ownership of capital would be no danger. The capitalist would hasten to share his profits with the workers, and the best remunerated workers with those suffering from occasional causes. If men were provident they would not produce velvet and articles of luxury while food is wanted in cottages: they would not build palaces as long as there are slums.
