Be careful to weed out marketing myths that have no basis in economic reality. The big money comes to other sports because there are equipment standards defined enough to allow independent companies to produce accessories, e.g. balls, racquets, etc., profitably, and to demand star players for endorsements. That will happen only when certain changes take place on the foosball landscape.
Being an expert or professional foosball player does not necessarily qualify someone to make determinations about the future of the sport. At present it appears that many top foosers either don't realize what is in their best interests, or have knuckled under at the threat of being blackballed from participation.
That said, we must give credit to some elite players who have tried to make changes, and some of you know who they are. Certain steps could be taken that would not only make the current foosball industry much more profitable, but would make some of our top athletes very wealthy men. And money at the top would resurrect our sport, causing an influx of players like happened in the seventies.
