Education doesn't necessarily mean knowledge and many rich people don't even have a degree because they thought its useless and not completely related to knowledge and skills. Education is the key for survival not for success so don't get confused between both cause it is different and knowledge is powerful in my opinion.
Actually, education without knowledge means nothing. But if someone inherits a lot of wealth, he must be able to manage it, otherwise he will lose everything very quickly. But money is a big power, the rich get a lot of influence, even without a good education.
