If the high ticket prices guaranteed him a first-class concert experience (no bright cellphones in the air, etc.) then at least the high prices would have some justification. But as it is, they don't when the experience is so poor.
Usually, with other luxury goods and services, the prices are outrageous, but at least you can count on a premium experience. You're not going to buy a Bentley car and get the same crappy treatment you get at a Chevy dealership, for instance.
This may be beside the point to market demand for tickets, and more of a systemic problem for lots of things. Maybe there's an increasing number of people who just need to appear awesome on social media, and are willing to pay more of a premium for second-hand, blurry proof of attendance. I know it's a cliche at this point, but with concerts it makes me particularly sad that people can't just be where they are.
