Difference between stages of socialism and communism. So I have often heard and read the socialist society and communist society being described as being in different stages low socialism being perhaps moments after the revolution, the implementation of capital at the hands of the workers through the proletarian state. Mid level socialism being the development of the implemented capital to increase productivity and quality of life for the workers. 

My questions being if I have gotten this idea of graded socialism right? And if the difference between high socialism and low communism would be the state dissolving, what would differentiate the steps of communism?
