btw there is huge controversy / debate surrounding the idea of 'base intelligence' (or the "g-factor as it is known in psychology). One may argue that the intelligence factor in respect to earnings that you refer to is toppled by economic supply and demand as demonstrated by the high wages earned by top footballers, models, artists etc that is due to neither chance nor 'base' intelligence (whatever intelligence may be). But that's for another day!
I am sorry, I hadn't considered that at all.
But would it be worth thinking of those that elevated the people into the positions in the first place? For example it is the manager that originally bought the football player, giving them the chance to succeed.
I have to say I am completely confused by this argument and I have no idea how to proceed, sorry.
