Look at Andres Segovia in the fifties. If you didn't know who he was, I could have told you he invented a transistor, or reviewed mortgages at the savings and loan, or toiled in any number of mundane professions, and his appearance wouldn't give it away.
People used to be serious, and you'd find serious people in every walk of life. Now all the Jeeves are dead, and everyone's either a high or low budget Wooster. Who allows their work or their art alone to speak for them anymore?
