Possible explanations: 1) our average age is older, so of course we have older actors, music, etc. People's tastes are more malleable in adolescence (usually), and adolescents are a smaller percentage of the population 2) the amount of recorded back catalog to listen to is larger 3) the percentage of music listening which is pre-20th century (mostly classical) is actually falling compared to 50 years ago, so it's not clear that we listen to less old music, we may just be listening to newer old music than Bach, Haydn, Mozart, etc.
