The goal of socialism should be to iterate itself out of existence. Its purpose is to keep negative aspects of human behavior in check for the common good, but only temporarily.
Socialism is a control system necessitated by the presence of severe human flaws. This is to say, if any semblance of equality is to be attained given these primal vices, some sort of socialism will be required.
But it is not an ideal. In fact it’s the opposite, and every responsible proponent of the ideology should realize that the goal of socialism should be to allow its beneficiaries to grow to the point that it’s no longer needed.
You can’t reach the ultimate goal of anarchy (self rule) or its younger brother, libertarianism, without the highest levels of individual responsibility and underlying concepts of mutual respect and connectedness. These are precisely the characteristics that immature and primal societies lack, hence the need for intervention.
So socialism is an intermediary phase between young, primal societies (which need the most controls) and those that require no interference from the state.
The goal of socialism should ultimately be anarchy.:
