I'm sure in every educational system you can use some form of metric to exclude low SES students and conclude that the system isn't behind or failing.

totally agree with you. was just pointing out a statistical quirk I thought added value to the discussion.

I'll even retract my point that the US maths education system isn't failing as a whole. When two demographics (30% of the country and growing) are being left behind by the system, then the system is failing as a whole. I really hope to see this change in the future.

…or maybe always attempting to look at systems as a whole and fix it as a homogenous unit might be exactly why it’s failing in the first place.
