Television entertainment is a discretionary expense. Comparing its pricing to the cost of bread, milk and eggs is irrelevant. Rather, the price of it and of all discretionary expenses must be compared to United States Disposable Personal Income.
If the measurement is not flattering, change the benchmark? The way to judge a price increase is to compare it with other price increases. Cable is up there with health care when it comes to aggressive pricing. If you think "you can afford the increase" is a valid argument (I don't), try comparing cable pricing with the median US wage over the past decade.
