Outside of a handful of institutions, the evidence of unthinking discrimination is slim too. It is true, of course, that men continue to earn more than women -- approximately $1 for every 75 cents that women make. But economists such as June O'Neill or Harvard's Claudia Goldin, who have accounted for different job choices, hours worked and time taken off for raising children, have concluded that it is these factors, not discrimination, that account for most of the difference.Maybe someone who knows more about economics can help me out here, but this doesn't seem to be Goldin's position at all! She's argued that gender 'as such' is declining in significance when it comes to the workplace, true. She's also noted—in her "pollution theory of discrimination"—that discrimination against women isn't driven so much by a desire not to interact with women (as is the case with racial discrimination), but rather a fear that women could reduce the prestige of a male-dominated occupation. To wit: "Men are averse to having women enter their occupation when women's productivity is not observable and verifiable to all."
