I definitely can't agree with Magestaff either. How many game slots are your using? Maybe you should start another game to see you if get the inequity.
I haven't found what you're talking about in any of my slots.
Three slots so far, and the inequality seemed for me to be present before any of the couples had children - so they can't use the mom with children excuse.
Maybe it is just that the peeps (men and women both) have differing priorities, but I sort of wish that the women were a bit more work oriented.
