It leads to K-shaped education where parents who recognize the deficiency of public education simply teach their kids math themselves or hire private tutors. Public education used to be a force for equality of knowledge in the country. Now it perversely does the opposite, all in the name of education!

At least in elementary school I don't see the deficiency in common core math compared to what I had 30 years ago. My kid has been exposed to a wide variety of topics sooner than I was, and she's way stronger in word problems on top of that. Do people have a specific complaint with elementary school common core math that we should be teaching but aren't, or vice versa? Or is it more problematic later?

One thing I notice is there seem to be far more students who finish elementary school unable to comfortably do basic math in their head (stuff like 17+36 or 144 or even basic multiplication tables like 38).

Except that's not what the data shows. The decrease is similar across performance levels.
