From the 1960s through the 1980s, feminists claimed that women earned only 59 cents for every dollar earned by men. The precise figure has since been revised upward to 64 cents in 1986, 70 cents in 1987, and, according to President Clinton (if he counts as a feminist), 75 cents in 1999, but their claim is that women still earn substantially less than men do. However, all of these comparisons ignore the inherent sex differences in dispositions and temperaments, and the fact that most women are not interested in making money as much as men are because they have better things to do than make money. More careful statistical comparisons of men and women who are equally motivated to earn money show that women now earn 98 cents for every dollar men make, and sex has no statistically significant effect on workers’ earnings. Adjusted for occupation and motivation, men today do not earn significantly more than women do.
The sex gap in earnings and the so-called glass ceiling are caused, not by employer discrimination or any other external forces, but by the evolved and internal sex differences in preferences, values, desires, dispositions, and temperaments. Just as there are a few exceptional women who are more single-mindedly motivated to earn money and attain higher status than the average man, so too are there a few women who make more money and attain higher status than most men.
