The Communist manifesto - Karl Marx , Friedrich Engels

A great literature, beautiful theory.

In my view, human are social animals. We collaborated to build great things. The better collaboration, the better products we produced.

There is one most important good we construct, that's the social structure. Bigger and moderner population needs stronger, more effectively social form. 

So we changed our sociality continuously. The process was not smooth but brutal in blood and steel.

The winner will be which system could generate more material objects and satisfy its citizen's needs. Beside of human network, there is one more key element. It's means of production. For example one person with a Death Star absolutely can beat a planet of Earth 2023.

However, the social structure which created to connect people. It will give some people at right position higher power than their peers. That's the beginning of unfair and unequal in human community. It could not be destroy with current science and technology.

Recently, the better system is the system that allow smooth transfer between classes. Let the crowd the hope to climb on power ladder.
