>Did Einstein say something profound about social issues or people interactions when he was younger than 40?

Jefferson was 33 when he penned the Declaration of Independence. Martin Luther King, Jr. was killed when he was 39. Marx published The Communist Manifesto when he was 30.

Seriously, this list could go on for ages. Dismissing the perspective of youth is as indicative of an ignorance of history as youthful naivete.
