Clinton touched on this in his HE thread, but it applies wherever kids are schooled. As far as I know, there are no schools in the 'western' world that include basic income management, let alone business and trading skills, in their school curricula. It is a feature of home-taught skills in nations or ethnic groups who have traditionally been the world's merchants.
My parents were teachers, and even though my father had risen to the post of Assistant Director of Education by the time Tanganyika became independent, he never had any 'wealth' until he retired in Penang and made friends with the Chinese, who guided his investment activities for the rest of his life. But that was still rent-seeking, not generation of wealth, and nearly a third of it disappeared between the date of his death and final probate. In the story Kawasaki uses to introduce his well-known book, I had a Poor Dad, but no Rich Dad to teach me. I went through life spending taxed income, and hoping for pay rises. I still don't really have the skills to identify and assess a business opportunity, or to do the things that make one come to fruition, although I've read plenty of books purporting to teach them.
I'd love to really learn and practice a little of that skill before I disappear from this earth.
