A large part of this is there are several companies that are effectively the modernized scalpers using very high dollar pay-per click advertising, and incredibly complex optimization methods to charge the maximum markup they can. Most of them use each other as well, in cooperation via affiliate kickbacks more than competition. Then, add in ticket brokers, with pre-reserved sets and blocks of tickets, feeding into that, and everyone is getting a cut. Not a small cut either. I do have evidence, as I worked for two of the companies for a while.
