My generation of Baby Boomers internalized them. To today, I sort out my own demons through what I recall of theirs.
But, that's me. When talking with Millennial clients, so many of them do the same thing with characters such at Tony Soprano and, yes, even anti-hero Saul Goodman (of "Better Call Saul").
The college curriculum didn't require them to take a course in Shakespeare. Their value system doesn't demand knowing anything about his works.
Even if a Shakespeare festival was free, clients I spoke with wouldn't bother going. They are more likely to binge watch episodes of "The Sopranos."
Likewise, most don't care a bit about Jay Gatsby, created by F. Scott Fitzgerald. Also, many university students have trouble sticking with any book, cover to cover.
Given the current trends, the odds are against a Shakespeare 500. No longer will the bard will relevant to society. Hamlet who?
