America has a very good education system against the backdrop of challenging sociological factors and mass low-skill immigration. In the PISA exam, white American kids outperform kids in Hong Kong and Korea, as well as western european kids of non-immigrant ancestry.

The American education system has major and important challenges, such as how to educate the large share of kids whose parents are economic migrants from non-English speaking countries. But those challenges aren’t relevant to the question of whether the U.S. can produce sufficient highly educated people domestically. China, meanwhile, doesn’t even participate in PISA outside four wealthy provinces.
