Robert C. Thornett in Quillette:
According to professor emeritus Andrew Hacker of Queens College of the City University of New York, less than five percent of Americans will ever use any higher math at all in their jobs, including not only calculus but algebra, geometry, and trigonometry. And less than one percent will ever use calculus on the job. Born in 1929 and holding a PhD from Princeton, Hacker taught college political science for decades and has also been a math professor. His book The Math Myth: And Other STEM Delusions argues that not only college students but high school students should not be required to take algebra, geometry, trigonometry, or calculus at all. Hacker points out that not passing ninth grade algebra is the foremost academic indicator that a student will drop out of high school.
Before the objections tumble forth, I should emphasize that both Hacker and I like math and neither of us wants to remove all math requirements; we want to improve them.
