More importantly why should it matter how someone defines success? I think the false and self-perpetuating notion of meritocracy is massively benefitted by the lowered expectations of the lower class. If I'm born poor, making it to lower middle class could be a huge success for me, if I'm born rich that same outcome would be a massive failure. Even to acknowledge that that is true is admission of how massively tilted opportunity is. If the poor and the rich had the same visions of success, they dreamed the same dream, do you think we could still say with a straight face that, really, hard-work is the most important factor in success? I don't think so.
