Kids learn to read, to write and to do basic math. Congrats, you can now do taxes and choose a health plan. Most specific tasks people complain about are just the application of other more general skills… And the people who make these complaints are usually the same ones who would fuck around in class and not listen even if they got the classes they “wish for”.
Music is also important, but your first sentence is bogus.
Taking the general lesson to the specific application can take training. Not everyone will understand taxes just by reading. Look at how many adults now a days don’t understand tax brackets as a good example. Tax brackets are something that is fairly simple to explain and yet we have a good portion of adults who don’t understand them and will insist they get less money while getting a raise.
My first sentence isn’t bogus, you just happened to understand the lessons and apply the to the specific. Other people find that challenging.
