“Capitalism” is a pejorative word invented by Marxists; I have no idea why those of us who support economic freedom should adopt our opponents’ terminology to describe ourselves.
The concept of anyone claiming to be pro-capitalism is bizarre. Are they really claiming to support everything that every businessman has ever done? Really? I don’t support capitalism, I support freedom, and one component of freedom is economic freedom, which means that the individual has the right to order his business activity as he sees fit - regardless of whether I approve or disapprove. It seems we understand other types of freedom better. Most of us support freedom of speech (or at least claim to), certainly that doesn’t mean we agree with everything that anyone has to say. Further, we can agree with the concept of freedom of religion without adopting the theology of every disperate religion on the planet. Yet when it comes to the economic realm there seems to be no shortage of those eager to enforce their will upon others.
I think ‘capitalism’ is an evolving word, the same as ‘conservative’ is. When the left tries to demonize something, it often is given a boost in peoples’ minds. Weird, huh?
