I can only speak to personal experience and the experiences of my girl friends and female colleagues. I don’t have any stats to fall back on, but a large percentage of the women I know (about 40-50%) are more educated than their husbands, are professionally more successful, which in turn means that their careers are more stressful and demanding than the guy’s and they make more money than their husbands.
Based on this, of course I expect that the husbands are going to pull their weight at home and not have the typical desi mindset of being waited on, hand and foot. I don’t think it’s right to emasculate the guy and say he become a househusband, but he should be supportive at home and make an effort to alleviate his wife’s household workload.
On the other hand, I’ve got girl friends who are stay-at-home moms with nannies to help with the kids and the housework. For these girls, I expect them to be understanding of their husband’s demanding careers - they shouldn’t be doormats for their husbands but should enjoy their time together as a couple and as a family.
But alas, I think I’m being idealistic - based on the threads posted - there’s seems to rarely be that middle ground and genuine partnership that comes not from splitting chores down the middle 50/50, but being supportive and ensuring that neither partner is overburdened or taken for granted in a relationship.
