“Capitalism is Free Enterprise dressed up as a moral system.”
Well, “Capitalism” was intended as a derogatory term (as are most -isms) because Marx wanted to destroy it.
Perhaps. I tend to think that Marx postulated that free enterprise would destroy itself by morphing -- emasculated of moral conscience -- to the soulless and unchecked practice of capitalism (which most wouldn't and still don't notice) on its way to socialism and eventually communism.
