It was inevitable once the court cases came down declaring college sports some some huge multi-billion dollar business. The truth is that it's marketing for colleges and loses money. Now that schools must pay up to the athletes, beyond what they already did with tuition, room and board, coaching, uniforms, medical, nutrition, facilities and more it had to be funded somehow. It's not "greed" because the schools still lose money on these sports. The court cases didn't really address the factual reality that fans cheer for the laundry and now we're paying for it. Make smart choices on what you spend.
As for concerts, the whole music industry did a 180. My father in law was part of it and saw it coming. A concert used to be a way to promote record sales. They didn't make any real money from the shows, they made money selling records (Dead being maybe the exception). Once music went digital to CDs, copying killed record sales and streaming was the nail in the coffin. Now, almost nobody makes any real money off of recordings, it all comes from live shows. So yes, that concert that was $12 in the 80s is now $180 because it has to fund everything.
