The vast majority of teachers that he had to deal with have no interest is seeing their students become more interested or creative. The teachers were there time-serving their job or focused on political activism.
He and I have had discussions over the years and one of his concerns is that creativity and interest in learning had to be encouraged in the younger students (primary school, grades 1 - 4). Instead it appeared to be beaten out of the students (figuratively speaking by teachers having little or no interest in providing such environments).
Certainly, teachers were encouraged to do certain activities but these things were not focused on encouraging students to think, to be creative or to be interested in learning.
His view was that by the time students reached grade 7, they were no longer interested in learning or thinking as all of this "stuff" was just plain boring and had no applicability to their social lives.
