I think a remedial class is pretty standard and finance classes are pretty common, but if you look at common core:

There are requirements for knowledge across the traditional academic divisions of Algebra/Geometry/Trigonometry.

I'm not arguing against teaching those things to as many people as possible, just observing that lots of people probably don't have that knowledge 2 years later and may be better served with more practical stuff.

On the other hand, I'm just some random person with a lot of opinions about education and little actual experience with it. A summary of my opinions is that a single social-promotion school track meant for everyone is completely awful.

I can't tell if you're seriously asking. But yes, tons of schools (in the US) are sub par, especially once you're one hour removed from a major city. From what I hear from cousins in West Virginia, it's actively getting worse.

Whether schools are subpar is a separate question.

I am saying that if you were in my high school and weren't expecting to go to college, there were courses designed for you across all disciplines to teach you practical life skills. However, I do think the school still required students to struggle through at least some of the standard curriculum.
