Another fact is the influence of hypergamy, which means that women typically choose a husband or boyfriend who earns more than she does. Funny thing, men don’t have the same preference for a higher-earning wife. While women prefer to have a higher-earning partner, men generally prefer to be the higher earning partner in a relationship. This simple but profound difference between the sexes has powerful consequences for the so-called pay gap. Suppose the pay gap between men and women were magically eliminated. If that happened, simple arithmetic suggests that half of women would be unable to find what they regard as a suitable husband.
Now Let’s look at preferences college courses. When you read a college catalogue, you find that there are no gender separations in courses of study. There are no male math or female math classes. But not nearly as many women as men choose math; women generally choose college courses that pay less in the labor mark such as psychology or sociology. Those are choices that women themselves make. Those choices contribute to the pay gap.
