I can sympathize with the idea of relying more on market-based approaches, but in my view that would require pretty aggressive anti-trust enforcement. In other words: I can see an argument for allowing monopolies but regulating them heavily (a-la the AT&T of old), or for light regulation in a highly competitive market (and relying on competition to prevent companies from screwing their customers).

It seems like most Republicans want neither significant regulation nor significant anti-trust enforcement, and I just can't see how they would honestly expect that to produce any result other than a small number of monopolies charging customers whatever they want and ramming whatever practices they want down their customers' throats.
