As encouraging as a healthy box office is for producers and investors, Broadway prices are absolutely ridiculous, with London and other cities also getting increasingly prohibitively expensive. It's a trend that surely can't be good for the long-term health of the industry because it makes it more and more difficult for people who don't have high disposable income to see a lot of shows and so develop a love of the artform.
Yes, there are initiatives like ticket lotteries, cheap day seats and discounts which offer more affordable seats, but often these are very limited in number and/or with poor views. And while a $100 ticket may represent a decent discount, it's still a $100 ticket.
Pro-shots are becoming more popular and while these have their place, I personally think that nothing beats the experience of seeing a show live.
The economics of theatre, especially musical theatre, depresses me, because I don't know if there's a solution for the problem. Theatre is inherently expensive for a bunch of reasons I won't bother getting into, and the vast majority of shows don't make back their money. This means that investors look for higher returns for those small number of shows where they do make a profit to make up for the flops. This in turn drives ticket prices even higher, so it's a vicious circle.
