The single-income household is rapidly becoming extinct and more and more women are bringing home a majority of the income. As women gain more responsibility in the workplace they haven't been adequately relieved at home and in the community.
Generally, discussion of unequal duties in families is reserved for book club, lunches, play dates and frustration when other family members aren't pulling their weight. I rarely hear men speak of concern for the well-being of their significant others when it comes to equal workload and pay.
There are all kinds of people telling women how to change their behavior to attain higher pay, flex scheduling, respect, etc. The dialogue needs to include men's responsibilities in possibly changing their schedule to support goals and family needs.
