A recent poll discovered an unsettling trend emerging for the first time. American families whose household income is $75,000 or less now have zero dollars of discretionary income. According to Luker, that means about 75 percent of the country can never responsibly afford to go to a live professional sporting event. Franchises want them to be fans, to buy the gear and pull for their teams and watch the telecasts the leagues are paid billions for. But they don’t need them to come to their stadiums. There are, right now, plenty of rich people who love games. The prices reflect that. The reason sporting events cost so much now, Luker’s research shows, is because they are designed to be affordable only to those making $150,000 or more a year.
