I think we significantly overestimate how much school actually matters compared to family milieus. My wife and I highly value education, so regardless of when the school says children should learn algebra, I am already tutoring my 6 year old in basic algebra. If school did nothing other than be a daycare for my kids so we could work, they'd probably still be better educated than most kids going through public school because my wife and I will make sure of that because we teach our kids a lot on our own (and we're not hiring tutors or after school programs). If schools were more rigorous then it would save us time from having to do a lot of the educating ourselves, but it won't change family values.
