The problem with Track and Field worldwide is that it's too compartmentalized. It's every man for himself, and it begins to cannibalize itself. Look at the major-leagues in essentially every major sport: NFL, premiere league, etc. They all have major sponsors that are funding the sports themselves. The athletes from those major sports earn a salary from the leagues/club owners who have incredibly deep pockets. They are then also able to supplement their salaries from their own sponsorship deals. Tom Brady makes money from the NFL, who has major deals with beer brands, insurance companies, car companies, etc. and supplements it with his individual sponsorship with Under Armour. Track and field is a major enough player to garner those huge sponsorships, while athletes can supplement their salaries with individual deals. Suddenly, we're no longer relying on the good will of individual federations, but the contractual obligations of a worldwide league that can mandate X number of appearances to qualify for "majors" akin to the majors of tennis and golf. It's really just a reorganization of money that already exists in the sport, but re allocating it for the betterment of all of its stakeholders.
