$13 gets you a nice entree in most any US city. Not white table cloth service of course, but you can find good and healthy food. Especially if we are talking just about the entree.
I usually don't spend less than $15-20 at fast food. But often it's multiple burgers without a bun, and a couple of side salads.
If you want to watch stuff that's not on Netflix, when you start adding in $7.99 for Hulu, $9.99 (?) for Disney, $14.99 for HBO, etc then you're getting into the same price range you used to pay for cable. Netflix used to be a much better deal when it had a much larger movie catalog, but as content owners have cut back how much they are willing to license to Netflix (and/or made it more affordable), it's not such an amazing deal any more.
I'd gladly pay a provider $30/month if they had all of the content that was available. I don't think music streaming would be nearly as popular if you had to subscribe to a half dozen different providers to hear all of the music you want.
It doesn't even have to be a monopoly, providers should set one rate for their content, and others can buy it and monetize it any way they want.
