A controversial new book by "Tiger Mom" Amy Chua, says some cultural groups are superior to others.
Chua highlights Jewish, Indian, Chinese, Iranian, Lebanese-Americans, Nigerians, Cuban exiles and Mormons and says they have three qualities that set them apart.
On Amazon, the write up for the book says, "A superiority complex, insecurity, impulse control—these are the elements of the Triple Package, the rare and potent cultural constellation that drives disproportionate group success."
Cain told CNN's Chris Cuomo , "We have, throughout history, said certain cultures are better at certain things... we do this correlation all day, I don't understand the controversy here."
Hill weighed in as well but took the opposite view saying: "She's not saying certain groups are better at certain things. She's saying certain groups are better at life, which is a whole different kind of argument."
