I went to a Montessori school from pre-K through 6th grade. I totally agree with this article. It is not easy to make this work on a public school-sized scale. The problem in education is not funding. We were a private school, but we made it work on a shoestring.
The biggest problem with public school is school size and class size. The last century of school building built prison-like megaliths, when it should have built a much more distributed system. Class sizes under 20 and schools under 120 at least through middle school would raise a far less pathologically self-centered society. But most people who vote/make decisions would have to care more deeply, so I think it's a no…
This is a big if. Until the 1990s, class sizes routinely exceeded 30 and school sizes 500 in former Czechoslovakia, but I wouldn't call us "pathologically self-centered society".
As for self-centeredness, shrinking family size might be the true reason. Only children tend to be a lot more pampered than kids who were born into a family of six. In China, they are called "Little Emperors".
