What makes you say so? I don't see the evidence that it's actually making anyone any happier. Instead, the data I've seen shows that
women are less happy than they used to be and
I think there's entirely plausible arguments that two-income households just wind up wasting resources chasing positional goods.
Sure, my wife's a scientist and I'm
much happier for it. I've never clicked well with people that aren't basically like her and I don't really understand other people's motivations in life. What I see when I look at the evidence though is that modern, anti-gender role norms aren't making society as a whole a better, happier place. Many men and women really
are quite happy in more traditional family arrangements. Bombarding people with the message that this is wrong and oppresses women isn't helping society. I'd much rather we present
options to everyone, but accept that men and women have different preferences and stop insisting that we need to shoot to achieve income and career parity between genders.
