The Statists will admit that Government enables these monopolies to exist, but they still blame it on Corporations, but change the topic to the influence of Money on Government.
Nah. They will point to the fact that some areas of business are just natural monopolies. Don't get me wrong - regulatory capture makes it even worse than it would be otherwise, but even though it is fairly free from regulation and many of the last mile problems I don't see 47 companies offering satellite cable.
The corporations are doing what they always do - charge whatever the market will bear. Regulation is required anytime you have a monopoly, no matter how it got there. Obviously regulation that encourages competition so as to minimize the need for future regulation should be preferred.
I'd argue that the best solution is to break up the vertical integration. Have a traditional utility (cost-plus basis) own the last mile wires. Then let anybody sell services over them. The service providers would not be allowed to own the utilities, but otherwise they would be free from regulation. The utilities would just charge you a monthly fee to maintain the lines, and would charge a flat rate to anybody renting rack-space to provide services - they wouldn't be in a position to choose winners/losers/etc.
The idea is that regulation of some things is necessary, but we should try to structure regulation so that we minimize its scope.
