I think as the pendulum moves more to the right that it will happen.
In other words, there will be big families again.
Couples who are MARRIED to each other, with a MOTHER who is ready, will, able and DELIGHTED to do so, will have to emerge in our society.
With the record track Americans have for "pairing up," having casual sex," "project" parents, living in sin, matriarchal families the NORM and NOT staying VERY close to God via ATTENDING Mass together as a family, I seriously doubt if the average SPOILED-ROTTEN American and his family (note the male possessive pronoun) will ever emerge.
I can't imagine Americans giving up their "stuff" or deciding to become CLOSER to God: it's TOO hard for them. It requires self-SACRIFICE.
Do you expect anything altruistic of Westerners as a society? Those who are practicing Catholics do that, on pain of sin, but practicing Catholics seem to going the way of the extinct do-do bird.
Just my observation, kiddo, nothing more. I'm already "out of the loop," being old, but I DON'T see much light at the end of the tunnel.
