I know the best way to measure whether a field is artistic is market capitalization. Video Games are more art than movies because they make more money. So what is the most art? Sun Tzu was right when he guessed 'war'. Government and private military organizations get more money than any other industry, even if we discount domestic military groups like the NYPD. Not only that, but that means that the US government is the single greatest patron of the arts. I guess all those lefty liberal arts type should really love it or leave it, huh?
