With the release of suppressed technologies, humanity would be able to live in TRUE communism, because there would be no need for money anymore
And I believe this was the original intention of the communism ideology but it got perverted by the dark forces.
The issue is that you have all the historical evidence and the current way of thinking to argue against communism. But think about the future, think about the level of technologies so advanced to the point we do not need to work the way we do now in order to sustain life. We do not need gas, coal and oil and many other things, which would free up so much labor and "economic" potential. Of course this would not be established overnight, but we do foresee a period where money would be gradually phased out of our system with the release of advanced technologies.
Also spirtually, if we really learn the law of love and service to others as we go down the road, even if we do need to work the way we do now, we would have our incentives aligned because it's not about the self anymore.
