Mathematics education in the United States has been in constant flux since the post-war era. The objections some parents have against “Common Core math” (which, incidentally, is not mandated by the Common Core; that is merely a set of uniform content standards) are the same objections parents had against New Math in the seventies.
My personal opinion is that the US has a bad case of Not Invented Here when it comes to pedagogy (half structural racism, half vestigial anti-communism, half class warfare, and half other things) which is then amplified by inconsistent funding and limited federal oversight.
Even if you burnt every grade school math textbook written after 1950, the problem would still persist.
