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.
It's meant to be absurd. Buried in the absurdity is a grain of truth.
The problem is, neither the arts nor home economics are valued in the education sphere and we don't base education policies on science.
As an example, an elementary music teacher I know said "in a school year I will have seen each child for 24 hours. That's not enough time to reach them some music theory or how to play an instrument."
