If the artists are willing to say sell tickets for $50.00 and the demand is such that some resell to $400.00 the same seat. Is it the fault of the ticketing system ? Who is the victim ? - The artist who could have make more money (but then they could have price it better) - The fans who are basically competing to see that show ?
Scalpers are optimizing the market.
Maybe the solution to mitigate scalpers would be for ticket holders to only be able to resell their tickets through the same platform. Then the artist could decide if the fans can resell to the platform at face value, or for a profit. Then the artist could decide if the ticket can be sold by the platform with a markup or not.
Basically given the power and control to the artist.
