The IFBB gives their members NOTHING. If I am wrong here and the IFBB does give the pros something I am not aware of please tell me and I will be sorry for saying this.
OK - well - the IFBB, being the dominant bodybuilding organization and through its promoters, gives the athletes a place and venues to compete in order to win prize monies. With that, the IFBB also gives us the place to have expos related to bodybuilding and supplements, and in turn, provides many people with jobs, and the means to advertise a product, which brings in revenue, which lets the supplement companies or another other type of related company offer a contract to the athlete. Being in the IFBB increases the value for these athletes, and perhaps can (but not always) open the doors for more endorsements, prize money, guest posing, and a bigger fan base. The IFBB does not give back in monetary means, but just being at an IFBB show provides many people with a sense of focus, a means to make money, etc.
Now, I am not using other federations don't do the same thing, or the PDI won't, but at the moment, that is an answer to your question.
No- they blackmailed suppliers and supply systems and threatened to drop them if they worked with any other companies. Competitors were dry and paralyzed.
No - they didnt. They said that if you want your product in their stores, then they need to be guaranteed the lowest price available, and first basis of the product availabilty. It is your choice whether or not you want to be in Wal-Mart. They don't blackmail anyone. As a supplier, you choose what where you want to be.
