Capitalism is deeply unjust. It is a system under which labour power has itself become a commodity and is bought and sold on the market like any other object of exchange. A condition of neo-slavery like this has been historically presupposed by the concentration of ownership of means of production in the hands of a minority class and the consequent emergence of a propertyless class for whom the sale of their power has been their only source of livelihood.
“You should therefore know that there are two ways to fight: one while abiding by the rules, the other by using force. The first approach is unique to Man; the second is that of beasts. But because in many cases the first method will not suffice, one must be prepared to resort to force. This is why a ruler needs to know how to conduct himself: in the manner of a beast as well as that of man.” — Niccolo Machiavelli
