This is precisely why all of those people who bray about deregulation and the free market are either deluded, or in on the scam
In many cases, the free market approach works in theory, but not in practice because theory little things like buying influence, gobbling up companies to make local monopolies, dividing territory to make local monopolies, etc don't exist. The folks who keep saying "the market will fix everything" look at the theory and ignore that the theory also includes a public with access to enough data to make an informed decision (no hiding charges below the fold - i.e. advertising $50 a month and then adding in $30 in "fees and taxes") and with enough choices to be able to vote with their wallets.
I would love for the free market approach to work with Comcast. Really, I would. Sadly, Comcast has taken the free market, bent it over, and is currently doing some unspeakable things to it while saying they need to buy out Time Warner Cable so they can "serve the customer better." (I think "serve the customer" is cable-speak and I don't think I want what they really plan on "serving" us!)
