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.
School also doesn't teach you how to get dressed or wipe your ass but you still learned how to do those things.
Some things are supposed to be taught to you by your parents. There was nothing stopping any of us from sitting down with our parents and learning how to do taxes which is exactly how I learned about it.
