Well...that's capitalism everyone so blindly loves because it's "American" to love it unconditionally. Owners are going to charge as much as they can until fans stop paying. Candy bars, gas, mortgage rates, labor costs...all subject to the forces of capitalism.
The problem is, folks tend to only love capitalism when they benefit from it. Owners LOVE capitalism when it allows them to increase prices and generate more revenue, but they HATE capitalism when they have to pay market rate for labor. The same discussion is happening right now all over the labor market, from fast food workers to engineers to CEOs.
I know right, folks being completely hypocritical when it suits them should be no surprise to anyone.
