Marx and his co-worker, Engels, consistently argued that socialism (or communism, they used the terms interchangeably) could only evolve out of the political and economic circumstances created by a fully developed capitalism. In other words, production would have to be expanded within capitalism to a point where the potential existed to allow for “each [to take] according to their needs”. In turn, this objective condition would have created the basis for a socialist-conscious majority willing to contribute their physical and mental skills voluntarily in the production and distribution of society’s needs.
