Who Decides What is Art?

While watching the two reboots of Romeo and Juliet in the 1996 Baz Luhrmann and the 1961 film version of West Side Story, I'm struck by two things:  How well they've both aged (although the casting of Natalie Woods is a different discussion. .  ), and how they were created to be accessible for their culture/audience to create their own meaning and relevance.  I chose the above picture because I think Banksy is an excellent, current day example of creative people pushing the arts in a direction that makes it challenge the authorities of what should be considered art, just as those two films did during their time period.  The division between "high" culture and "low" culture is being destroyed even as we speak.  As an example, I remember when Lin Manuel-Miranda went to a White House dinner in 2009 to celebrate "poetry, music, and spoken word."  At this performance the opening of his new project, Hamilton was performed for the first time.  Here's a link to watch on your own. It is interesting to watch the crowd!  At first laughter, then realization of pure genius. All done at the White House in front of the President of the United States. In many ways, it's an example of how suddenly the culture and background of "old, white men" can be transposed/transferred for the rest of us.  Like Romeo and Juliet the story doesn't change, just the intended audience.  I see this as a source of a power grab by the "folk," the "popular culture" takes the material, then shapes it as necessary for their own meaning in their own life.
