Yes, it does end up in classrooms. Feel free to look up the metrics you're talking about. Here [1], for instance, is the student to teacher ratio which has continued to decline dramatically over the years. And this difference becomes even more stark when contrasted against many of the countries, particularly in Asia, with substantially greater educational outcomes with far less in the way of every resource.

By "most" metrics the US should be having phenomenal educational outcomes. The one variable that's not controlled for is the quality of students. Also, I put "most" in quotes because it's a weasel word - to my knowledge we outperform on every single typical educational metric, except result.
