The US saw declines in math performance while remaining flat in reading and science.

The US didn’t even crack the top 10, which shows that, as a country, the United States needs to take education more seriously. Since manufacturing jobs have been shipped to China, that is basically a dictatorship, and therefore the wages are cheap, and since we only provide for free education up to 12th grade in highschool, if the US doesn’t do anything soon to improve things, the US will just become a country full of uneducated and unemployed people. And we know how good that will make things overall.
