So then let's have a few separate paths instead of only one curriculum. I believe that there is a lot of value to a basic algebra + personal finance + probability math track that helps a future plumber understand everything they need for their career.

Depriving college-bound students of calculus, though, is a bad move. A lot of philosophy also involves calculus-related arguments (ie if we cut up space in really small pieces, what do we get?), so it has applications outside the STEM fields.
