Students at a prestigious business school (where they are trained to make successful businesses) are more likely to focus on their business's wellfare than on what's fair
People likely to succeed in managing a business will be low in trait agreeableness. This is well known and has been known for years.
Despite the apparent implication of "disagreeable" people being bad, it means that such people are more focused on themselves, unlikely to be swayed by the opinions of others, and more self serving. It's a trait that allows businesses to succeed, by having the owner focus on the success goals of the business instead of the success goals of other people.
Contrast with high agreeableness, where the person is more externally focused. Psychologists and nurses would typically be high agreeableness.
Everyone has an agreeableness score, and it's a bell curve. The fact that there are people who aren't "fair" is compensated by people who are exceptionally giving.
