My sister works 32 hours a week, yet earns more than her husband. Sure, technically she doesn't work full-time, but I see no classical gender wars scenario here.
My wife recently stopped working. I love my work, she started to resent hers and would rather spend her time on other things. I earn enough for both of us and with her now doing more of the housekeeping I have more free time as well. We're both happier this way, so where's the problem?
