Personally, I believe there is some truth to this...especially the part where the author advised men to "never listen to what a woman says -- always pay attention to what she actually does instead." I would modify that to say that as a guy, one should not only hear or listen to what a woman says but also observe and keep note on what she does...much more telling and true.
As to the role of money and the need for sex as items of attraction women see in men...both are factors but I think it is more of a function of age. In other words, the younger the lady, more likely the attraction is more of sex appeal but as the lady comes of age, the obvious power and neccessity of money becomes more important...not neccessarily the fact of having large amounts as such men tend to be scarce but the income potential becomes more important later on in life for mainly legit reasons...cost of living, raising kids, health care costs etc.
In considering the author's cry for women "to jettison the manipulative greed, which so characterizes their gender, and seek out men of any status, as apparently nature have intended" is at best idealistic for all case scenerios...it could happen if the the lady actually has the money and is out to satisfy that natural post-30 increased sex drives ladies tend to have with just any guy that floats her boat..but for the rest of the world....nada..and understandably so!
