Because You Are Stupid
MLB's business model is based on monopolizing baseless loyalty to market a game where grown men play in the dirt and scratch themselves for three-and-a-half-hours. Blowhards like George Will and Billy Crystal can evangelize about "the beauty of the game," but that’s really what it boils down to. You exist to pay player salaries and feed the ego of billionaires who own teams. And for what? So they can work six months a year, bang the hottest girls on Earth, and retire at thirty-five-years-old.
If you look at the price of concessions, tickets, and officially licensed team apparel, it should read like a giant "fuck you" because that's what it is. The only power you really have as a fan is to stop showing up. You know it. Baseball knows it. And that's why nothing will change.
