The question is, where can it be done profitably--or at least bring MLB enough talent to justify the expenditure? I think that it would be wise to spend sums that can be recouped through the combination of talent acquisition and local income (ticket sales and concessions). There's no need to do this in Japan, Taiwan, Korea or much of Latin America--though they might be wise to make sure those leagues can continue, especially some Latin ones. OTOH, there's no point pouring money into a bottomless pit. I suspect the best model is spending small amounts of money in a very strategic way. One problem is that, unlike the selling of consumable products, sports usually require a synergy between players at several levels and fans to have positive finances. It wouldn't hurt baseball to try and figure out answers as to how to accomplish this, but to start with relatively modest sized pilot projects.
