Also from the article:
Quote:
One of the most startling statistics in Farrell's book is that unmarried women end up earning more money than unmarried men. Farrell explains that unmarried men end up taking more fulfilling jobs because they lack the responsibility of having a family or being a caretaker. While women take on work as a part of their identity, focusing on how they can earn enough money to support themselves. When they do that, they are more willing to relocate and spend longer hours at work.
"The genders are interchangeable when you take away the division of labor that occurs with children," said Farrell.

That, IMHO, is an important point to consider.
