One of the problems of lower socioeconomic class students is that a whole host of STEM fields are blocked because they lack the math and computer knowledge coming out of high school.
You need to hit calculus senior year or getting into STEM is gonna suck hard. I had friends in engineering school who first hit calculus in college, were failing so dropped the class, but kept attending the class. They understood it was the gate.
Without the math, the only jobs in reach are "softer" fields: social work, criminal justice, nursing, etc. This has an attendant depressing effect on the uppermost level of their salary.
Accelerating math will benefit a few high flyers, but actually devoting resource to better teaching the math that is there will benefit a broader section of students.
