Yes and I'm just explaining why. Saying "Americans are so stupid because of the education system" is a drastic oversimplification.
Even going back thirty or forty years when McGraw Hill was way more relevant than it is today the testing in the subjects you listed was much better.
Demographics are the majority of the issue here and realistically speaking it's only going to get worse.
They want stupid people here that will basically just be consumers.
The United States is an occupied country and no one is coming to save us.
