Rubenstein made billions in private equity and by his own admission watched his friends make even more owning baseball teams. That should tell you something about how profitable this business really is. I’d love to know why so many fans are convinced owners need a cap when franchise values have exploded and we still have no idea how much money these teams actually make. If the owners are struggling so badly under the current system, open the books and prove it. They won’t. And this is why!
