We can create a classless society but any economy requires a medium of exchange, money, to work. Socialists are handicapped by such a notion and their ignorance of money. It is the unjust private control of money that creates the classes and the problems. Just as the ancient Greeks realized 3000 years ago creating and issuing the money exclusively for public purpose is the most vital prerogative of democratic self-governance, that any government that did not control the money was controlled by those who do. thus it must be a public utility.
