Book aims at writing a story about desired social change. The author considers the subject of "sexual economics" in his book.
The author claimed that his work was aided by the book The Transformation of Intimacy by Anthony Giddens.
He states that sex has become cheap and identifies the key technological "achievements" that made it so: the pill, high-quality pornography and online dating services.
Cheap sex caused massive slow-down in development of committed relationships, especially marriage.
Increasing number of women has been risking their fertility as a result, bumping up demand for infertility treatments
Cheap sex reduces motivation of men to achieve. Some stats: 39% of women vs 33 percent of men earned at least bachelor's degree (in age 25-35), more women than men in paid labor force.
He attribute the changes to technology drivers rather than political will. The changes include decoupling of sex from committed relationships and altered meaning and structure of marriage.
This is another scientist (in this case sociologist) among growing number of those who express their concerns about politicized academic culture, which slows the pace of science.
