Ran across this item on general player wages and competitiveness on the Sports Economist, an interesting looking blog but without an RSS syndication feed in sight (it uses atom).
Here is a concrete example. The U.S. will produce numerous soccer superstars in the future. But they will all go to Europe unless our clubs pay competitive wages. MLS rules are currently designed to limit player wages. Until that changes, MLS will be a business with a sensible plan, but a second rate league on the world stage.
