Debate topic: Sports today is a matter of business not pleasure?

Proof that sports is a matter of business: players (ex: Manny Ramirez , JaMarcus Russell, & LeBron James) whining about not being paid enough money, despite being paid thousands (sometimes millions) for their job. They are paid far more than firefighters, police officers, & teachers despite there not being such a dire need for entertainment as education & law enforcement. Players are willing to leave teams & abandon fanbases (Nnamdi Asomuagh leaving the Oakland Raiders for the Philadelphia Eagles recently) for other teams & fans just to get a bigger paycheck when things are all said & done.
