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.

Taxes are a certainty for sure, but any time you don’t know what to do there are instructions to reread or internet to consult. I will also admit that I pay a CPA to do it after 18 or so years doing it myself: the filing part is simple enough, but knowing how the code changed so I can minimize tax expense for the next year is work.
