Certainly, as a history teacher myself, I do not use calculus whatsoever. My barber, YouTubers, and auto mechanics have no need for Calculus in their jobs. I agree, it should be taught, but only to those who need it in their future careers. You say it CAN BE taught at home. Yet, many of my low-income students do not learn about financial literacy at home. Their parents are working all day. You might’ve had the privilege of learning this at home, but many students do not.
We can’t rely on parents to teach kids to be productive citizens. Look at the complications with sex ed. Some parents feel uncomfortable about the subject and don’t discuss it at all with children. Kids have to use Google, which is a horrible tool to learn sex ed.
