You give significance to managing funds because they play a major part in our lives. You said learning it is worthwhile. If it is so important, why it not be taught in school? What private matter would you say you are referring to? How can an individual learn effectively without given instructions? Even creatures teach their youngsters and we are better than them.
All that is important is to be taught at school. There will be fewer poor families and poor nations if all have a superior comprehension of how to deal with our funds.
I also feel surprised when you ask like that because in schools in my country there are economic lessons which generally relate to money and procedures for managing finances. So if you ask like that, is it possible that schools in your country are not taught economics or how to manage money so you can avoid difficulties through success in a particular business field? Because I'm not sure that there are no economics lessons at school except for those who basically don't go to school at all so it's still considered normal to ask questions like that.
