The time frame isn't really relevant.These semantic problems go away when one acknowledges that a socialist can aspire to achieve public ownership of the means of production without viewing it as feasible now and immediately. It seems that some people assume someone who advocates that is "not a real socialist" if they don't try to force public ownership immediately or don't view it as currently achievable.
One's vision of an ideal society can be quite informative about their position.
If one wants a flavor of socialism that is devoid of capitalism,
then whether it's immediate or the product of slow evolution,
the inherent empirically observed problems remain.
