The word capitalism has become unusable. When most people hear the word capitalism, they think of the current system of collusion between business and government, collusion between business and the military and a financial system that privatizes profits and socializes losses. The technically correct name for the current system is mercantilism or fascism, but those words have long been forgotten. M...ost people now use the word capitalism to describe this kind of system. So when Christians try to defend capitalism, people read them as defending the current system, so they lose credibility. Putting the words pure, or biblical, ore free-market on the front does not help, because the meaning of the word capitalism has gone beyond the point of no return.
