I believe that professional athletes get paid a disproportionate amount of money for the little contribution they make to society. CMV

According to Yahoo Sports (not necessarily the most credible, but other sites corroborate roughly) the average salary for a NBA player is $5.15 million, MLB $3.31 Million, NHL $2.4 Million and NFL $1.9 Million. This is all per year, and the average. I know that high salaries can skew averages, but these values are more than what an average person would make in their entire lifetime.

I get that these athletes have dedicate their lives to playing a sport, but these salaries are not reflective of their contribution to society. I think its a shame that public service professions don't make respectable wages for the dedication they have to society (for example, teachers, firefighters, EMT's etc...)

Now I know someone is likely to make the argument that the number of athletes is a significantly less proportion of the population than some professions that we'd all agree should get paid more for what they do, and that society couldn't afford to raise everyone's salaries (also the economic consequences). But I still think these athletes get paid much more than they deserve.

Salaries do not need to be proportional to the contribution to society, it is a simple matter of supply and demand. 

The supply of world class athletes is incredibly low. The demand is incredibly high because companies are willing to pay tons of money to advertise at sporting events that tons of people watch. 

It is about economics, not contribution to society.
