“Capitalism as an economic system is essentially defined as the process of private expropriation of public wealth.”
Okey, so it is not the other way around? Socialism is expropriating private wealth (or better worded “value creation”).
If I own my body, I own the labor of my body. If I want to give that away for free or for ten billion that’s up to me, and my surrounding will see to that my actions are fair.
As many others have pointed out both here and all over the internet, the critique taken up in this article “against capitalism” is in fact against socialism. Free market proponents hate bankers being bailed out. Bailed out by whom? The government. Let that sink in for a moment or lifetime.
