pardon me, but just WHEN do men and husbands take any responsibility for NOT having more children?....just when....
Great question!
There is no doubt that along with women living some fantasy "I can have it all when ever I want lifestyle" men are becoming just as infantile with their Peter Pan attitudes. I look first at women because it is women who are the driving force in socialization. Men tend to be driven by physical urges whereas women used to be driven by stability and safety. It seems as the "nanny state" takes on more of the masculine role of providing stability and safety that the roles which built a healthy society are breaking down.
Because these roles are breaking down we are seeing lower birth rates. You will see what this means by looking at Japan, Italy, Greece, and France.
