How is personal freedom acheived in a community?

It is extremely hard for someone born in 1981 to ponder the thought of personal freedom being acheived solely from their community . However, Marx and his ideas came from a much different time period then the one I was born in, and I am trying to really grasp his ideas of freedom with their being no aspect of individuality.
Marx believes that the idea of class should be eradicated entirely, leaving it up to nature. The era in which Marx lived was a time of the really rich (bourgeousie) and the peasants, and not much in between. How much better it would be, so he thought, that everyone could be on the same level of class and financial standing. If everyone was of the same social status then everyone would be happy and basking in the glory of being a unified state. I truly believe that Marx was trying to create a government and state where the citizens would all be working to obtain the same goal of being a profit weilding state, with peaceful and loyal subjects who all profited from their labor that aided the countries profits. In theory, this would lead to achieving the goal of freedom within the community, not as individuals.
The conflicting question that keeps running through my mind is did Marx foresee what would become of his idealogy? Did he forsee the iron curtain and opression that woud fall on the lives of millions of people that he thought would indeed be set free by his ideas? Could it be possible that his idea was innocent and naive when he thought that people should all be the same? How can we be free without individuality? We now know for certain, that that is most definitely not possible as it has been proved in history. The one thing I pray, is that this idea of Marx, does not repeat itself in the future, because as he speaks about fetters, I most certainly can't even phathom the future societies being chained down under persecution of such a monstrosity of an idea such as freedom in communities.
