Monopolies are like porn. I can’t describe one to you but I know one when I see it. OK, so maybe the term monopoly is technically incorrect in this instance…but not by much. In my area of service it’s Time Warner Roadrunner, AT&T DSL or nothing. While there is competition, there isn’t anyone that can deliver the same speeds as Time Warner, making the price difference between the two services make sense.
The idealist would say that this is a good situation. There are products to serve almost everyone, regardless of income. You get what you pay for and when you pay less you should expect to receive less.
