> Paretto’s corollary law was that 50% of the work was performed by the square root of the company. Could we just harness the power of the IQ120+ people and feed all the rest of the population?

What makes you think the square root of the company neatly aligns with high-IQ people? There are plenty of smart people who use their intelligence to find ways to avoid work, or to get others to do work for them, or to just amass power/influence in an organization by increasing head counts and making busy work, etc etc. Why assume that “smart” equals “having the company’s best interests in mind”?
