The poor can never rise in American? Wrong.
Amy Chua, the “tiger mom,” has a book w her husband Jed Rubenfeld about how people are successful, titled The Triple Package. They say the study that claimed the poor cannot rise made a huge error; it did not include immigrants. They are many large cases of rising from poverty to wealth - in the US - now! Their triple for success is: superiority complex, insecurity and impulse control.
