Well let’s 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 don’t 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 aren’t smarter especially when the employees are in very important position.
