For the sake of the graduating students, they should be prepared for a bit more than an entry level job if they want to advance.
It used to be that high school graduates went on to very lucrative careers in trades and skilled labor, where not only algebra but trig are requirements.
The requirement here is that they be able to be productive members of society - and that’s a big more of a requirement than bagging groceries at the local supermarket.
Here’s a list of industries from the BLS. I see a whole lot of industries that high school graduates can enter without expertise in algebra.
