Preamble: It's not us. It's not humanity. It's our culture.
The essential point to note is that for all your complaining, your schools are doing just what you actually want them to do, which is produce workers who have no choice but to enter your economic system, pre-sorted into various grades. High school graduates are generally destined for blue collar jobs. They may be as intelligent and talented as college graduates, but they haven't demonstrated this by surviving a further four years of studies – studies that, for the most part, are no more useful in life than the studies of the previous twelve. Nevertheless, a college graduate wins admittance to white collar jobs that are generally off limits to high school graduates.
What blue and white collar workers actually retain of their schooling doesn't much matter – in either their working lives or their private lives. Very, very few of them will ever be called upon to divide one fractional number by another, parse a sentence, dissect a frog, critique a poem, prove a theorem, discuss the economic policies of Jean-Baptiste Colbert, define the differences between Spenserian and Shakespearean sonnets, describe how a bill passes Congress, or explain why the oceans bulge on opposite sides of the world as a result of tidal forces. Thus, if they graduate without being able to do these things, it doesn't really matter in the slightest. . . .
The schools turn out graduates who can't live without jobs, but have no job skills, and this suits your economic needs perfectly. What you're seeing at work in your schools isn't a system defect, it's a system requirement, and they meet that requirement with close to one hundred percent efficiency.
