The book seems to be written for women who have struck out dating men who are smart and have a large earning potential. The women I've met will tolerate all sorts of quirks if the man has a great job, or inheritance, fancy car, and lives in a big new house and has a vacation home in another clime.
Now if the man has none of the above, the man will indeed have trouble as soon as the facts present themselves.
I never had any of those things, and I never had any difficulty. I even pretty much live the American Dating Dream, I married a 6' blonde.
