I generally agree with Roy's thesis, and particularly appreciate the depth he goes into, though it's not new to me. A good book that covers one element of it is Warren Farrell's Why Men Earn More: The Startling Truth Behind the Pay Gap -- and What Women Can Do About It.

As on the Amazon.com page:

"Why do men earn more than women? Because they deserve to, argues this contrarian challenge to feminist conventional wisdom. Men work longer hours at more dangerous and disagreeable jobs. They more readily accept night shifts, hardship postings to Alaska and entrepreneurial risks. Men get in-demand degrees in engineering, while women get degrees in French literature. Female librarians earn less than garbagemen, not because of discrimination, but because so many applicants compete for the safe, clean, comfortable, convenient, fulfilling jobs women prefer. Indeed, the author insists, statistics show that women and men with equal experience and qualifications, doing the same job, for the same hours, under the same conditions-get paid the same. Farrell, author of The Myth of Male Power, usefully points women towards high-paying, male-dominated fields that are becoming female friendly and suggests that ambitious women marry stay-at-home husbands."
