I read through this, but I'm a bit lost. You realize you can use money to purchase income generating assets? In fact you realize that most people accumulate money for the purpose of purchasing these income generating assets?
If I have a lot of money I can easily change it into a lot of wealth and a lot of wealth can be liquidated into a lot of money. And no, nobody who is actually rich cares about their education or intelligence because neither of these are able to generate anywhere near the kinds of returns from simply buying up large amounts of income generating assets.
It seems like the author discounts the value of any investments you can purchase, which leads him to the conclusion that entrepreneurship is the way to go. As others have commented, this isn't borne out by history.
