In a discussion about this picture "Math student here. The majority of the math that they teach in high school is completely worthless to the average person. The curriculum here in Ontario is particularly bad: there are a bunch of mandatory courses that are all building up to calculus, but then the first calculus course isn't required, so most students who don't like math end up with a knowledge of a bunch of concepts that aren't even mathematically useful without calculus. And honestly, I love calculus, but it's only useful if you're going into science or engineering. For most people it's too abstract to have any real use.
