Typically speaking, studies have shown that women who don't drop out of the work force to focus on child rearing tend to advance and earn at the same as men with the same or similiar education and skill set. Now that's not to say a glass ceiling and the good ole boy network doesn't exist but it does demonstrate that there is more equality in the work place then some would claim.
Isn't that in fact, beside the point, the take away from your statement is that women who choose to have children and who choose to take care of them for the first 6 months or a year are punished the rest of their lives for the fact that they chose to procreate. Yet the same misogynists who would punish women for taking the time to procreate are the same people who would deny that woman the means to terminate that pregnancy if she chose and are generally the same people who preach that woman's highest calling is procreation. Your statement obviates all these conflicting and contradictory social factors.
