It's not just a men thing from what I'm seeing around me. Women are also disenchanted and going their own way, or getting married and deciding not to have children even when they can. I see this among my friends too. I've not come across any men yet [I'm not saying they don't exist. I just don't meet them]. It has been the women each time.
The system doesn't suit men or women right now when there is so much stress on both sexes. And we are not encouraged to value family or children.

In my family the case is clear. Between us, there are 15 adults [including partners and past partners] and a total of 9 children. I've done more than my share with 4 of those! ALL the male members of my family wanted children and the ones that didn't have children didn't because the female members didn't want to.

I think you underestimate how pissed off women are too.
