Lucchino and Henry want civilized spending
See, in a perfect world, every team would have a General Manager/Front Office that could make good moves, while spending as little money as possible. In this world, the top-tier payrolls would have a distinct advantage. If every GM was skilled at their job, and there wasn't much difference between the minds that are within each organization, then the extra money that a club would have, would play an even more significant role.
