Those are exorbitant prices. 

A lot like the money paid to NFL and NBA players.  (my opinion)

Here are some definitions of 'exorbitant' that I found online:

--  unreasonably high
--  going far beyond what is fair, reasonable, or expected
--  exceeding the bounds of custom or reason
--  highly excessive
--  really just too much
