Exodus 20.7 Thou Shalt Not Steal

The Seventh Commandment forbids the taking of someone else's property and the right of one to possess property. But the commandment covers many other areas of our lives as it relates to our neighbor's property, including his own life. If one has property and the right to own it, does this automatically preclude systems of government that do away with private property? Are these systems of government evil? What about the poor, the wage earner, the employee and employer?
