I'm still confused. The article is written by a man and his character is male. He got hit on by Angrenor when he was wearing an amulet of Mara, but decided not to marry a homeless guy. It's not especially backward thinking to want your spouse to have a job other than panhandling.
Article notwithstanding (I admittedly only skimmed it and in retrospect it was probably a bad example), but in general, while society tolerates women in the workplace more today than in the past, there is still a HUGE double standard. Women's average salary for the same position is still less. More women still hold more traditional roles (secretary, nurse, etc., or as in the TV series Flash Forward, where the Japanese girl is asked to serve the others tea), and for the most part, again while tolerated, it is still frowned on for men to stay at home while women bring home the money.
This was depicted at length in the film “After six.”
Just a couple hundred years ago it was almost a law of the "nuclear family." Many films have mocked this, more recently Pleasantville. Men carry the briefcase, do the commute, make the money at the office or the factory, women stay at home, raise the kids, cook the meals. It is tradition, and as someone here already pointed out, it goes back to millions of years of tribal hunter gatherer genetic conditioning. Women weren't (most often) seen as strong enough to hunt, or were considered property (which is still the case in more countries than not today.)
It isn't that we can't overcome genetics, but you have to realize its been only a few thousand years of real technological change against millions of conditioned instinct. Granted the context of the moment takes priority over traditions of the past based specifically on functionality and necessity, however traditions based more in BELIEF are MUCH slower to change.
That said, I am personally quite relieved to see the trend shifting. But that doesn’t mean it has entirely been shifted, and people still take advantage of that on both sides of the six line. It is times when this becomes particularly nasty (gold digging, male chauvinism, etc.) where I like to remember a song Tori Amos sang on Strange Little Girls… “If there’s war between the sixes then there’ll be no people left.”
