The only one who focused on this political fact was Bernard Shaw, who said the following: “To begin with, the word Capitalism is misleading. The proper name of our system is Proletarianism.” [See Capitalism = Proletarianism] Barring people from doing whatever, can be called a political or coercive act. In that case Proletarianism [aka Capitalism) is a political system.
I know that people who defend Capitalism focus of the market transactions between a employers and employees, pointing out the benefits to the economy — technological innovations, mass production, and better living conditions. And this is true, except for the existence of the unemployed, the underemployed, and poverty.
I tried to understand the characteristics of capitalism (=proletarianism) by the model of two persons marooned on an island. [See Three forms of slavery: chattel slavery, serfdom, and wage-slavery]
There was one transaction between Crusoe and Friday which has bothered me. This is the situation in which Crusoe and Friday share the island equally, but Crusoe has a rifle and bullets, and the island if full of wild animals which can easily be hunted with the rifle. Crusoe offers Friday the use of the rifle on the condition that Friday is to provide to Crusoe half of all his kills. Friday agrees because he will be better off hunting with a rifle rather than by some more primitive mode. He will have more food with less effort, and more leisure. Here we have a situation in which Crusoe reaps a profit from Friday without doing any work himself. We can also call this an employer-employee relationship.
My point here is that you can have a market economy without slavery, serfdom, or wage-slavery. Or, put otherwise, a market economy can exist without Proletarianism (aka Capitalism).
What prevents Friday from making his own rifle and bullets?
On the island, nothing.
On the mainland, a government with a patent law!
