ELI5:Why they don't teach how to do taxes, credit cards, insurance(health and auto), loans, investments in general public schools.

It seems like these are all important things everyone person will have to deal with in their life and yet, they barely scratch the surface on teaching these in schools.

They teach the underlying skills you need to figure these things out on your own. Reading comprehension, a bit of research, and some basic math is all you really need to figure out how all this stuff works. If schools had to teach you every life skill you'd need, we'd be in school for the entirety of our lives. The purpose of education is to teach you how to reason about the world around you so you can better face the vast variety of challenges life will throw at you, not to tell you the solution to every problem you will face in your lifetime.
