A: Intelligence

Intelligence has nothing to do with wealth, according to a US study which found that people with below average smarts were just as wealthy as those with higher IQ scores. If you have an average score, around 100, you do however make about 6,000 and 18,500 bucks less than someone with a 130 or more IQ. Do rich people generally think they’re smarter than everyone else? Does it take smarts to become rich and stay on top?
