Not sure there’s a more cut and dry everyday example of a consumer-abusing monopoly than Live Nation/Ticketmaster. I remember when I was a kid Ticketmaster’s fees were usually flat and maybe like $2.50 per. I don’t go to too many events these days, but when I do it appears seem like 30% is the typical fee, and that’s on tickets that run over $100 apiece to begin with. DoJ keeps talking about reviving antitrust. Can’t think of a better place to start.
