So… pretty much any ticket you buy for anything has to be bought through Ticketmaster now, with “convenience fees” of about 25%. There’s no competition, usually no option of calling the box office to buy tickets directly, and often no option of GOING TO the box office to buy tickets directly.

Basically, Ticketmaster has a choke-hold on the market and gets their cut on everything.

It’s hard to imagine other fields where this would be even remotely legal.
