Major league baseball's current revenue-sharing system, even while bettering the game, is too burdensome on the wealthiest clubs which are substantially subsidizing some of their opponents, according to Boston Red Sox principal owner John Henry. Team ownership must bring in roughly $2 on every $1 invested in order to break even, Henry was quoted as saying in Thursday's editions of the Boston Herald. The Herald said his comments came in an exchange of e-mails with the newspaper over the past week. "Baseball has to address the disincentives created by large-scale transfers of revenue from successful clubs to less successful clubs," Henry said. "At high enough tax levels, the incentive is to invest somewhere other than in baseball." He said the disincentives are just as powerful for lower-revenue clubs as for the higher-revenue clubs. "The Red Sox have taken an aggressive stance in investing in all aspects of the franchise," he said. "But one has to wonder how many teams will do so when the financial risks often outweigh the potential financial benefits." About $50 million to $60 million of the Red Sox money is flowing per year to less successful clubs, Henry said.
