I do not know what the stats are as I do not know all the rich people in the world but I guess you are right. Rude and unfair is the only way to make yourself extremely rich. They also have to be very mean people who know how to get around even the law (like with how they can escape tax for example) to keep accumulating money,,, more so than general people.
Crypto sadly seems to attract same types of people:(
They definitely understand how to and are willing to bend the law for their own purposes. Usually, they all have giant networks of people from all spaces, including tax and law and politics. They achieve their goals with means that the ordinary guy simply has no access to. That's the difference between them and the rest. Ultimately, they become so big that even individuals can be considered too big to fail.
