I don't believe any of the socialist movements in the past were implemented with the design of creating a society where the majority of the population would live in poverty while a chosen few would live as royalty. But, the idealist socialist "vision" can't figure in the flaws in human nature. Once established, this unfortunate trait happens and we know how it ends.
Also, if this socialist paradise existed, why was private gun ownership so threatening?
For any lurkers, history did not begin when you were born. It doesn't help to model our system after European countries who depend on us for defense and are still broke.
