Query: Ruby Payne claptrap

This book is designed to alleviate the poverty of the author at the expense of children in classes with teachers who have absorbed her awful message. As a cultural anthropologist with 35 years of research experience in urban American, I can say without hesitation that this is not just over-simplified; it is a set of racist stereotypes that have been adduced without any kind of systematic or acceptable evidence. She has made a fortune as a "motivational speaker." She is no scholar, and her work can worsen the very problems she claims to be trying to solve.
