"Men and women have competing reproductive goals"

This Chart Shows Who Marries CEOs, Doctors, Chefs and Janitors: "When it comes to falling in love, it’s not just fate that brings people together—sometimes it’s their jobs. We scanned data from the U.S. Census Bureau’s 2014 American Community Survey—which covers 3.5 million households—to find out how people are pairing up. Some of the matches seemed practical (the most common marriage is between grade-school teachers), and others had us questioning Cupid’s aim (why do female dancers have a thing for male welders?). High-earning women (doctors, lawyers) tend to pair up with their economic equals, while middle- and lower-tier women often marry up. In other words, female CEOs tend to marry other CEOs; male CEOs are OK marrying their secretaries."

Female Hypergamy Is Real: "Some readers would demur that hypergamy isn’t sex-specific, pointing out that men also strive to find the best possible lover they can get. My rebuttal is two-part: One, men don’t date up based on social, economic, or occupational status. Men, if and when they are able to date up, do so based almost entirely on women’s looks. We’ve all seen or experienced how men trade up when they’ve come into a financial or social status windfall — younger, hotter women...  So male hypergamy — what is more precisely termed “physiogamy” — is different in kind from female hypergamy.
