Most of what Americans think they know about capitalism and communism is total nonsense. Here’s a clearer picture
1. Only communist economies rely on state violence.
Obviously, no private equity baron worth his weight in leveraged buyouts will ever part willingly with his fortune, and any attempt to achieve economic justice (like taxation) will encounter stiff opposition from the ownership class. But state violence (like taxation) is inherent in every set of property rights a government can conceivably adopt – including those that allowed the aforementioned hypothetical baron to amass said fortune.
In capitalism, competing ownership claims are settled by the state’s willingness to use violence to exclude all but one claimant. If I lay claim to one of David Koch’s mansions, libertarian that he is, he’s going to rely on big government and its guns to set me right. He owns that mansion because the state says he does and threatens to imprison anyone who disagrees. Where there isn’t a state, whoever has the most violent power determines who gets the stuff, be that a warlord, a knight, the mafia or a gang of cowboys in the Wild West. Either by vigilantes or the state, property rights rely on violence.
