Consider: If your kid is a bad student, pointing out that the neighbor's kids down the street are excellent students doesn't really help your kid pass math. Telling Microsoft or GM it should just "be more like Apple" doesn't mean they could succeed following Apple's strategies.
The US system has been very different from these other counties for quite a long time. We have different values, different skills, a different history, a different political process. It's quite possible that you simply can't get there from here.

America is just NOT LIKE a tiny european country, and the ways IN WHICH they are different are relevant to what is politically and practically possible.
