Our National Parks: Of, By, and For ... the Concessionaires?

Nowadays, it can cost upwards of several hundred dollars per night to stay in a lodge or hotel in one of our citizen-owned and much-beloved National Parks. You can also spend hundreds more partaking of amenities like camping, rafting, climbing, horseback riding, hiking, eating, etc.
 
So, what's the common link between all these things? 

Private concessionaires.

Now, is it a problem that the superintendents of some of our most beloved National Parks seem to have an, er, unhealthy relationship with these highly profitable operations?
 
Watchdog group Public Employees for Environmental Responsibility (PEER) believes it's a serious problem. So do investigative journalists at the Seattle Times.

On the other hand, the Obama Administration doesn't seem troubled at all.  

What do you think?
