As writers and fans have grown to have a stronger understanding and interest in the business side of baseball, it has become more common to measure the success, or health, of the game by things like the revenue generated by the teams. This is not unlike measuring the state of the American economy by looking only at the Dow Jones Index. It may give a good heuristic of the economy, but it misses a lot of important aspects. Why, after all, should a devoted fan care how much more money the rich people playing and running the game make? I do not enjoy a day at Yankee Stadium, the venue where I usually see most of my live baseball, any more knowing that the Steinbrenner brothers are having a good year. In fact, I enjoy the experience less knowing that so many of the people behind the scenes, doing things like selling concessions or tickets are not compensated well.
