A Boring Dystopia

What you're talking about happened way before the Ticketmaster-Live Nation monopoly became a thing. Today if you want to make a medium to large concert you have no choice most of the time but to use a Live Nation venue and Ticketmaster for tickets. For example Live Nation owns all large concert venues in Toronto and I recently learned they've purchased the well known smaller venues over the last few years. They're now in a position to extract more value from fans and performers. Similar to how large grocery chains can extract from both customers and suppliers.

You should see the video though. It explains things well.
