Does he talk about the financial and social segregation aspects of new ballparks? At the Met, everyone was essentially together. Some tickets were more expensive than others, of course, but it was a communal experience and if you put up the price of a box seat you could be sitting next to a CEO. The Metrodome allowed for private boxes, which created huge revenues for the club(s) and allowed the privileged to drink better liquor, eat better food, and avoid mingling with the masses. Target Field extended this model to include not only private boxes, but segregated the entire section behind home plate. Again, more revenue and more tiers of social segregation. Attending baseball games, like so many other activities, has become much less of a "shared social experience" in the last 50 years. Perhaps a small cause, or perhaps a small result, of the polarization that is so apparent in our economics and our politics.
