Education only teaches us about rules, discipline, how to behave, build dreams, doesn't make us rich, only a means of bridge to success. Education here is very important whether it's a school for the rich or poor but does not determine one's fate. They can be successful and rich because of themselves, their efforts and never ending prayers.
Here in my country we treat education as a special factor or a special ticket to get a good job, education taught me how to become a good citizen, obey rules and regulation and be a good employer but as I remember in my 16 years of education up to my college days all that the education instructor taught is to become a good employer but never have had tell to become a good investor or businessman. I've been born and raised in a poor family which my parents instill in my younger mind to finished my studies to get a good job but they never told me to finish my study and get rich. But now those advices that I've gained from my parents and environment has now changed, i am still struggling in life but at least changing my mind set from my younger self I treat it as a good start for a new beginning.
I see what you are saying but another problem I notice with our current education system is the massive streamlining of everything. There is not enough flexibility and also insufficient individual programs. Yes I know there are thousands of programs by now, but everyone has a very specific set of talents. Yet people are sitting with 600 or even more in one room listening to the same stuff over and over again for decades. The only thing that often changes in the professor's presentation is the date in the top right corner, not the content.
I think you are right that essential stuff like investing and taxes aren't taught at all although everyone faces it from very early on. Picking the right insurances, saving money and many more things that are essential to a content life are not part of the educational schedule.
