I'm naturally suspicious of anyone's "shoulds" about education unless they base them on research in sociology, psychology, and/or pedagogy. Otherwise, they are usually based on the person's own personal history and our interpretation of our history is always suspect and biased. (The author's disclaimer means my point doesn't apply to the linked article.) It may be the case that the author's high school experience wasn't worth the time, but that's a retroactive observation. It's probably true that for some people high school is a net good and for some it isn't. But unless you have an effective way to distinguish one from the other before they go to high school, it's hard to draw actionable advice from that fact.
