EDIT: A lot of you are reading into the tweet while still somehow agreeing with the overall message. No one is saying we should eliminate music programs or that we should teach toddlers about healthcare plans. The tweet is making this thing called a --checks notes-- joke, that also conveys the message that schools could teach more practical skills that young adults will need going forward.
I had to take a "home economics" class in highschool. However, you could test out of it. I was unaware that you could do this, so I had to take it. They taught us the very basic us tax form, how to write a resume, how to write a check (yes I'm old). It was very remedial stuff that can easily be learned if you need to know it. The 1040EZ tax form is for someone with a regular job and it has a set of instructions that goes with it. In fact, all us tax forms have a separate instruction sheet unless you have a very niche problem such as repayment of unemployment income or something like that.
