"What if women don’t need guys any more, and guys don’t care?"
That's the title of a response to an earlier Globe and Mail article on changing gender roles. The author in that earlier work asserted that:
Women are flourishing in this new world, but many men aren’t. Men have always defined themselves as providers — it’s the main source of their identity. What happens when they aren’t needed as providers any more? What happens when their sense of purpose is lost? The answer is, they become unmoored. They stop being adults
The response asked the following questions:
... [A]fter a while I started wondering if it really was a bad thing after all. It only makes you nervous if you believe men are losing a position they aspired to: breadwinner, provider, working stiff. What if feminism only recognized half the problem, i.e. the female half? What if it wasn’t only women who’d been shunted into a role they didn’t want, what if men had as well?
Elaborating, the author mentions that
Think about it. What do those men lucky enough to strike it rich do once they reach a level of real income security? Some stick to the job, because to be that successful usually requires that you love your work. But a big proportion ditch the drudgery first chance they get and start enjoying life. They do something they’d like to have spent their life at all along but couldn’t, because of financial pressures. Well, the more successful working women out there, the more men find themselves in the happy position of having a choice in life.
Add in the current divorce and family law situation, and the return on investment into a career has dropped somewhat as well. With the wife being the initiator of at least 2/3 of divorces, she'll probably land up with the kids, the house, and her income, while he'll likely still be stuck footing the bills. (That study on why wives more frequently divorce their husbands than vice-versa does attribute this difference in large part to current family law by the way).
