US-centered response, assuming the article is about US education.
The article is off track vs what I observed with my kids math (typical middle of the country small public hs). Nobody gets to do trig until they've done boat loads of stats.
The thing I saw missing was the kind of top notch teacher that can inspire and intrigue the students. This can only be addressed by paying teachers much more. That's not going to happen. Our school only had one "real" math teacher, and he retired last year.
Paying more goes hand and hand with testing teacher (or holding them responsible for students grades), and generally that's not very well received by teacher unions.
The example I always drop is my ap calculus teacher whose students had an average test score of a 4.7, but the ap physics teacher didn't have a single student get a 5. They never shared their average for obvious reasons, but I'd assume it was closer to the national average of 2.3 based on what I heard.
Clearly the school had students capable of putting in the effort, if the teacher was capable of teaching the material.
