You are absolutely right that controlling for time worked, experience, education, etc makes virtually all of the wage gap disappear.<p>Nonetheless, that is totally irrelevant to this topic. Regardless of the reasons, women do earn less than men on average. Since the topic here is about spending money (i.e. consumption side), then the amount of income available to a person to spend is absolutely relevant (regardless of the origin of the disparity in income). The reality is that most women are making less than men and yet goods tailored towards them do cost more.
