I suspect this study is bunk. One way or another, they are missing something.
Or it's true in Britain, but not America.
Women may say that because they don't want to seem shallow, desperate, grasping, and (worst of all) inferior. Saying they aspire to the man who "has it all" goes against 50+ years of feminist indoctrination. When it comes to people in general, watch what they do--not what they say.
