Quantify hard work and "grit" into a unit of measurement - call it a wK.

Mitt Romney's sons simply don't need the same amount of wKs to be hedge fund managers as a black kid born in west Baltimore. The kid from Baltimore who becomes a hedge fund manager is an anomaly - extraordinary. To "exhaust all excuses for success in life other than grit, dedication, and plain old hard work" is to expect the majority of any under represented demographic to be extraordinary, which just doesn't add up.
