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.
