Three Quotes from the Kindergarten Paper

This explains a lot. I don't got to kindergarten.

The difference between "small" and "large" classes is only 7 students (15 vs. 22 students). That doesn't seem like a huge difference. I would expect a much bigger difference between classes of size, say, 40 and 5.

One unstated and usually overlooked implication of that paper is that most teachers, i.e., those teaching anything other than kindergarten and those who are less experiecned kindergarten teachers, should be paid nothing above some bare babysitting minimmum as they add nothing to their students' future earnings. That is obviously absurd which tells you how much value the paper has.

I appreciate the authors writing this paper. The fact that it is useful to have been written is disturbing.
