The thoughts of Eton Dave

This is from Eton Dave's peroration about the "broken society":

"Of course, circumstances - where you are born, your neighbourhood, your school, and the choices your parents make - have a huge impact. But social problems are often the consequence of the choices that people make".

Dave made good choices; he chose to be born the son of a wealthy stockbroker and the daughter of a baronet, chose to go to Eton, chose to join the Bullingdon, etc...

Why can't we all be as wise as Dave?
