"Those damn MBAs" is a lazy scapegoat.
Doesn't matter anyway. If you've chosen big-corp adtech, datasci, analytics, optimization, etc for a career, not "loving" it is not an excuse.
Tickets to sports, concerts, Disney and other big-name attractions have been increasingly steadily, outpacing inflation, for at least the past 25 years. You've really missed the boat if you think this is in any way, "short-term".
There's no reason it isn't just an interminable series of short term steps.
Bob Iger was Disney CEO for 15 years, during which he bought Pixar, Marvel and Lucasfilm, opened parks in Hong Kong and Shanghai, and set the stage for Disney+. The company's valuation increased better than 5x.
Michael Rapino ran Live Nation and merged with Ticketmaster in 2010, becoming CEO of the new Live Nation Entertainment, and depending on your choice of start date, has 5x to 10x'ed the company's valuation. It has bought multiple event management companies, created artist management divisions, and owns and operate concert venues across the U.S. and internationally.
Jerry Jones bought the Dallas Cowboys in 1989 for about $140 million. Now, it is the most valuable NFL franchise, at about $5.5 billion -- a 40x increase. He built AT&T Stadium, moved the team HQ and practice facility to become the centerpiece of a massive real-estate development "The Star," and has been a pioneer and leader among NFL owners in boosting revenues from television contracts and other external sources.
These are not "short-term steps."
My guess is it's MBAs. They figured out that you can squeeze people more and so they're doing it.
Before everything was optimized by a business person with as spreadsheet, people would set prices by reasonable guess, and that guess would simply be lower than optimal.
For instance there's a village shop where I live. You can get a hand made sandwich for two pounds. Similar factory made sandwiches at Marks would easily be closer to double.
