I don’t think that we are powerless to control the market, but that in this instance there is really no need to do so. In my opinion Beyonce has no obligation to perform live for any less than what she believes her performance is worth. There is no shortage of artists that are willing to perform for much lower prices. But if you insist on listening to a live performance of Beyonce specifically than it is really on you if you are unhappy with the cost. I agree with you that we shouldn’t be slaves to the market and would gladly support intervening when the marked doesn’t produce desirable results for the people. But it’s not like people are dying or even really suffering from lack of access to Beyonce concerts.
