Because terrain parks cost an insane amount to build/maintain. I know for fact cat time at Whistler in the summer is $250/hour. Diggers/Coaches/Staff all have to get paid as well...
costs add up quick. The owners of the camps do well, but they aren't taking home insane amounts of money every summer.
Because the rich pay the mountains to charge a lot so the rich get better at skiing while the poor still struggle, its all a conspiracy, Obama is Illuminati, Bush did the Titanic.
