That article focuses on the number of jobs created which may be associated with Mitt Romney’s tenure at Bain capital, or while he was Governor of Massachusetts. This is over thinking it. The core reason Romney isn’t an articulate defender of Capitalism is that, for him, Capitalism is merely a question of managerial competence. Sadly, he lacks a principled understanding of Capitalism, and thus can’t defend it as a philosophy. Much like Herbert Hoover.
Someone should ask him if he’s ever read von Mises, Hayek or Ayn Rand.
