Sadly no, I can't think of anything crucial that answers your question.
Pop culture is an oxymoron. There is nothing really cultural about pop icons like actors, entertainers, & athletes. These folks may have their merits in their own fields , but they are not really changing the world for the better on a permanent basis. Ex: Michael Jackson is in no way equal to Newton, nor is any athlete equal in significance to a Galileo or Columbus. You see what I'm saying?
Culture use to be about the arts & sciences. People like Da Vinci, & Van Gogh, Newton, Einstein, Mozart, Vivaldi, Bach, Shakespeare etc.
