Wesupportgifted: You're just advancing the nonsensical notion that the highest in ability will necessarily be the wealthiest, the leaders of companies, entrepreneurs, etc.
Numerous scientific studies have been performed which consistently prove that the single best predictor of future wealth is the socioeconomic status of the parents. Not IQ.
Some HG+ people are introverts, who have no interest in leading companies.
Some HG+ people are risk averse, and prefer a steady job to entrepreneurial activity.
Some HG+ people reject the Wealth = Human Value paradigm, and find other, more meaningful ways to contribute to society. For example, Ben Franklin gave away the intellectual rights to the lightning rod. Jonas Salk did the same with the polio vaccine.
Many HG+ people seek employment that is intellectually satisfying rather than wealth producing.
And finally, many HG+ people fail to actualize their talents due to the challenges of low SES backgrounds, poor community understanding/support for gifted education, etc.
Finally, considering the size of the US labor force (approx. 155 million), there are plenty of available employees for Google in the top 1%.
