I live in a very traditional, conservative area and would have to say that yes, society as a whole seems to have very much a double standard for stay-at-home dads. I am extremely happy to have my husband stay at home, he is an excellent househusband and generally has a lot higher energy level than I do, allowing him to keep up with the kids along with the housework and other chores. That said...we're both getting awfully sick of people asking when he's going to find a job.
When I originally quit my job to strike out full-time as a freelancer, everyone thought that it was so great that I was going to spend my time raising the kids and "could help with household expenses too." These same people expected it would be catastrophic to us when my husband lost his job, and don't seem to understand why we're not bankrupt a year and a half later.
He is older, with more work experience and far more education, but we found that I make a lot more money with him home to take care of the house than we were able to make with him working out of the house and me working around the kids' schedules. Society thinks he's lazy or unable to find a job, and can't understand why I tolerate him still not having one. At least once a week some well-meaning acquaintance tells us of an opening they heard about, and they're all still puzzled when we don't pursue any of them. These same people even say that they know where I can find a job to tide us over until he finds one, because I couldn't possibly be able to manage without a "real job."
Thankfully, we put very little stock in what society thinks, and don't feel the need to explain ourselves. I sincerely hope that other potential stay-at-home dads and breadwinner moms will equally disregard these outdated and often unfair preconceptions about who should be doing what. Too many assume that stay-at-home dads laze around and still let Mom do all the cooking and cleaning when she comes home, and too many also assume that Mom couldn't possibly be making enough money to support a whole family on her own.
