Well lets take Elon musk for example he hires people that are smarter than him who works very hard to build his own empire and he gets more super rich and while their employees just gets their normal pay. This is how Billionaires get rich and their employees earn the little they do.
I dont think billionaires can do without some smart people around them, left alone they can only do as little as they can, and I doubt if there is any right thinking Employers that would even hire an employee who arent smarter especially when the employees are in very important position.
Right. Employers are given the full advantage to chose people smarter than them so that they can easily finish their jobs with almost perfection. And since they are more than good enough, employers will not spend more time anymore from training them as it seems their goals are in align with the employers goals. The smarter the employees, the higher the chances for the companys growth and success.
And Elon thinks that only the smart people are white people and he is firing all the indian from Twitter.
But the formula is correct - he has been very smart in hiring the wise and smart people working for him and getting rich.
