I am one of the exceptions that uses higher level mathematics on a regular basis at work. I agree with his theory that teaching everyone calculus, or preparing to take it, is not necessary for most. The problem I have is that he is looking at averages. In my experience, there are five tiers: counting, arithmetic, algebra, calculus, and higher math. The USA is simultaneously sending more people to the top two and bottom two, with the bottom two going from a small few to a real population segment. I don't even know if the worst public schools teach anything anymore or if they are just pseudo-prisons to capture taxes. I won't even go into the woeful state of logical and statistical knowledge. I don't know why those aren't core requirements for graduating high school.
