I agree with the author that knowledge and well-being are tied. But it is the desire and aspiration to learn and take all new things that ultimately leads to financial well-being.
The school teaches how the sciences, objects and situations in the world are called, the university teaches how to filter the flow of information from the world and take what you really need. The person aspiration to endlessly educate from the world and APPLY it for the benefit of himself and the world, including the financial stability, is what really should be counted.
Information is around you and all for FREE, the only thing you need - is effort and the ability to filter information, find reliable sources. While knowledge is power that is only true if you have a way to put that knowledge to practical use for the benefit of your own and the world.
Thats why huge market players like Binance and Coinmarketcap spreading educational materials in their Academies - they know what smart people really appreciate
Most people do not have the minds to learn things they rather not learn or care. I personally went to a year long coding school, it was just about teaching people C# and some other minor stuff, and at the end of the day I ended up getting a certificate from there that said I can code in C#, and at that moment I was actually at a very very very beginner level, not even like someone could hire me, I was that bad but at least I knew some stuff, nowadays I have zero idea what that was all about and can't do anything about it.
All of this comes down to one thing; it doesn't matter how much information is out there, if you do not want to learn, you will not learn it. I have learned Latin all by myself, still suck at it but I at least learned a bit of it all from studying from online courses, but I went to a year long c# course and couldn't learn a thing. This is exactly why people can learn what they want to learn, but if they dislike the topic you can throw every book at them and they will not learn a thing.
