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.
Unemployment is everywhere and lot of reasons are there why many doesn't have jobs but currently the fear of recession caused many companies including google, facebook, twitter, tesla, etc fired thousands of their employees to survive their winter. For us, we need to keep updating our skills so you won't be fired or can get a job in no time.
I do agree with you. while it might not necessarily mean School education, you do need the knowledge to manage the money you might come across. I can confirm to you that both the Co-Founders of the last organization I worked in were college dropouts and they did pretty well with the organization employing people with higher degrees and masters in the organization and we have seen this with those you listed too however, I believe we need some form of education.
