Here is some experience that I have had. In an inner city high school (math class), in each mid-thirty student sized class, there were about four students who made it their point to disrupt the classroom. Unless actual violence occurred, they were not to be kicked out. So the teacher could spend a large portion of the period trying to reign in a couple of students at the expense of the whole class. Add to that that the majority of the class had difficulty with, not just multiplication or division, but SUBTRACTION. This was an Algebra class, and the students had to be graded on their Algebra skills and judged on their Algebra proficiency tests. No homework would be completed, and no recourse could be given for lack of homework. 50% of these 9th grade students will not make it graduation. 3% will make it to a four year institution. Less will graduate from there. How is this different than working with professional engineers? Ones who could be fired or in some other way worked with? How is this different than working code where a solution exists? How is this different than working with other people who are looking for a solution as well? A better comparison would be to how you judge a prison guard in relation to recidivism rate.
