Opinion: Barack Obama and equal pay for women

Article here. Excerpt:

'So it's entirely possible that Senator Obama is a sexist, misogynistic creep who gleefully rubs his hands together and laughs demonically while scheming to persecute his female employees. Maybe he has nothing better to do. But far more likely is that the aforementioned factors explain his office's inter-sex pay differential. Perhaps his male employees work more hours, have been more likely to accept promotions involving greater responsibility, have more experience, sacrificed "personal fulfillment" and instead chose more lucrative fields, and/or have greater seniority. Whatever the reasons, I'm quite sure of one thing: The phenomenon is attributable to natural, market-based factors and not a conscious desire to disenfranchise women.'
