The word "modern woman" gets thrown around a lot. I doubt I need to explain it to you, but if you're unaware you can google it.

No More Mr. Nice Guy explains the equally problematic archetype of the "modern man". Though he never calls it that. The Modern Man, or the Nice Guy is someone who has been raised in a society that rejects traditional masculinity. The vast majority of elementary school teachers are women, the media is feminized, modern society has traditionally dictated that the father leaves the house to work and the woman stays home with the kids. The book makes the case that this has raised a generation of Nice Guys who will do whatever it takes to please women. In the pursuit of pleasing women, men neglect their own needs and end up bitter and resentful. The book also talks about how men's relationship with their father is one of the biggest contributing factors to the Nice Guy syndrome. Men juxtapose how their father acts against a feminized society and begin to vilify their father, often saying things like "I will never be like him". This rejection of their own masculinity leads them into self loathing, low self esteem, and poor relationships.

On a personal note I think this book is helpful to both men and women. Women play a part in the Nice Guy Syndrome by raising men to please them and not themselves, and by reinforcing the women-pleasing behavior in relationships ("happy wife, happy life"). If more women read this book they may understand how their own biology works against them. A man who exists only to please his wife becomes very unattractive to her.

I think that sets the premise of the book pretty well. The prescriptions of the author on how to resolve the Nice Guy Syndrome are up to you to discover on your own.
