The mobility of highly motivated people such as myself has never been greater,
But aren't you the son of a high flying oil company lawyer ? So how exactly are you an example of upward social mobility, the American Dream and all things meritocratic ?

No- the truth is the US doesn't reward hard work and merit - it rewards the individual in direct proportion to their privilege.
Those who are privileged, like yourself, wish to maintain their privilege - as Galbraith said "The fortunate find virtue in that which perpetuates their good fortune".
You can big yourself up as much as you like but I can assure you that I have met many many people who have exceeded your intellectual capacity (and emotional maturity FWIW) and yet own/possess much less than you I am sure - as will their children if the facts are to be believed on social mobility.
