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.
And none of those examples that you gave are taught in elementary school or highschool. They’re taught as college careers because there’s a breadth of knowledge required to specialize in those fields. We also have tax attorneys, and accountants who specialize in personal tax filing. They learned those skills in college.
