A key distinction in economic viewpoints that goes oft-unnoticed is between pro-business and pro-market. A good bellwether to where someone stands on the pro-business/market continuum is his/her stance on antitrust policy: pro-business usually favors incumbents, while pro-market calls for aggressive antitrust enforcement to facilitate competition.
“I would not dispute that even a monopoly-ridden market would be preferable to any economic system trying to operate without any kind of a market. But given the prevalence or the danger of substantial intrusion of monopoly into the market, the logic of the laissez faire defense of the market against state-intervention collapses and there is called for instead, by its very logic, state-suppression or state-regulation of monopoly practices, which one may wish to call, as Henry Simons called it, an instance of "positive laissez faire" or, as I prefer, as an instance of deliberate departure from laissez faire.” Jacob Viner - The Intellectual History of Laissez Faire (1960)
