Corporations, nor the government will have what is best in mind for the people unless the people direct them.
For many reasons I spend my own money to filter the water coming from the government with all of their "wonderful" regulations. If it was so safe why can't I put fish into it immediately after getting it from the tap?
I have no problem with Comcast or other ISP's doing common sense traffic filtering. I don't mind them giving priority to VOIP and video game traffic over P2P and other traffic.
Government can't do anything to corporations that the people couldn't. It just so happens that most people are apathetic and expect someone else to do it for them. That allows corrupt government officials to write regulations that will do nothing but benefit a few large corporations.
Have you seen the stock prices of the large insurance companies after the health care "reform" bill was passed?
