Since this thread was started to discuss the negative effects of the Japanese system, not the American one, perhaps you could enlighten us with some of those "ugly heads" in Japan.
Sorry to respond so late.
Granted, when it comes to Japan, this is something that I have only second-hand information on, not direct observation, so please take anything I say with a grain of salt.
Frederick the Great of Prussia created the school system specifically for the purpose of de-Christianizing his Lutheran population (i.e. do away with religious objections to his military programs), and effectively brainwash the populace into being cogs in a machine. The system is designed to create unquestioning foot-soldiers and officers.
This seems to actually fit into the current perception of Japanese culture. I hear many Westerners in Japan comment that they are all cogs in a machine, something that seems to definitely fit into Frederick's conception of what schools are supposed to create. Schools in America are notorious for
not teaching people how to think, and based on what I've heard from both Japanese students and Westerners living in Japan, I can only assume that Japanese schools are just as bad, if not worse.
Like I said, I've not been there myself, so my conclusions are going to be somewhat flawed. And I only have direct experience with schooling in America to go on.
I'm going on to quote Ewok's comment here:
Good at churning out people who do not complain, who will do as they are told, for as long as they are told, and will work even if its means they are physically and emotionally sapped.
If that is not how a "good" soldier will behave, I don't know what is. This describes Frederick's aims better than I could.
Considering the cultural differences between Japan and the United States, I can see how the school system could have different impacts on the society, but the core problems are definitely there, and they do have a direct impact on society as a whole. If that doesn't clarify what I'm trying to elucidate, well, I can only apologize for my rhetorical deficiencies. I have too many thoughts and too little time to get them all down.
