Life is a hustle and it's only getting harder. Attaining a good education when you're young and keeping your skills up to date is the only way the average person is going to make it in this world. After that, you really need to start educating yourself on all kinds of financial matters, learn how to invest in places like the stock market because as Warren Buffett says, the only way you'll get rich is having your money working for you while you sleep.
I like how you have put this.
Only a dumb person will feel education isn’t entirely necessary to attain and maintain wealth. You might not be educated in yourself but, I still see that to be more of a necessity but, successful or uneducated individuals haven’t attained certain level of success in life, they tend to seek an education or surround themselves with learned individuals to aid them manage their wealth. You wouldn’t want to surround yourself with those that know nothing, it will crumble all the efforts you’ve put in your building phase.
Knowledge and wealth cannot be separated from each other, because when we are rich we need knowledge to maintain the wealth we have. When we don't have it, then don't be surprised when we go bankrupt in a short time. Yes, you are right, some people are indeed very successful without education but they have knowledge and they realize it by recruiting competent people to help maintain and develop their business. Therefore, knowledge is always a basic thing that we must have in life, many people eventually fail because they cannot provide themselves with knowledge. Knowledge can not only be obtained through formal channels, but we can get it from anywhere (informally) as long as we are serious about looking for it.
