It’s a message that much of the media has been happy to spread, epitomized by an odd segment about rising food prices that CNN ran last week. The segment was supposed to show, in the words of a much-mocked tweet promoting it, “how badly inflation is hitting the middle class.” But instead of looking at a typical-size middle-class American family, it focused on a Texas family with nine kids, one that buys 12 gallons of milk a week. In the process, the segment succumbed to one of the media’s worst tendencies: taking a real issue and overhyping it beyond recognition.
