Since when does industry revenue dictate "high culture?" By this measure, reality TV shows would be the highest art form in the US.
Fortunately, people still value "real" high art in the form of opera, symphony orchestras, theater, etc. If it weren't for these folks (me included), we'd be knee deep in the plot of Idiocracy.
Interesting read. To me, culture is as culture does - though geographically speaking, the inertia of culture rather dictates what is acceptable in some instances and not in others. A little herd mentality perhaps. For me? Games all the way; perhaps with classical music in the background.
