One reason that ticket prices have gotten so high is that it's the only way for the artists to actually make money. They make nothing on the music streaming. The concert tix are still somewhat reasonable if you get the tix directly when they go on sale. It's expensive, but these stadium shows cost a fortune to put on. The problem is the secondary market and I'm not sure what the answer is. When Springsteen used dynamic pricing for some of his best tickets, people were outraged. It does suck that you needed to drop $5k for front of stage seating, but at least he and his team made the money. Ticketmaster took their few pounds of flesh also, but they get that on the secondary market for many of the tickets anyway.
I personally don't love stadium tours anymore. I think that's more about the bands that play stadiums than the stadium atmosphere. I saw Green Day and Weezer at Citi Field and liked it a lot. But G&R at Met Life wasn't great. I have no interest in seeing Taylor Swift, Drake, Beyonce....
I've been done with attending pro sports for a while. They're typically boring to attend (especially considering how many NBA/MLB games there are) and are generally better on tv. Especially since I don't have a huge rooting interest anymore. College sports are still much better priced. I got the Empire (UConn/Indiana and Texas/Louisville) seats for $125 per ticket. That doesn't seem unfair for two good games (I'll probably leave after the UConn game). Small theater shows are also still reasonable.
