After world war II, women went from a very small percentage of the labor force to around 50% of the labor force. Like blacks, Jєωs and ɧoɱosɛҳųαƖs, women are (as a group) recipients of university, government and corporate sponsored "affirmative action" programs. An incredibly small percentage of our nations annual wealth production actually goes to wages for what most people would consider as "workers." Unions have been destroyed, industries have been de-regulated and huge numbers of good jobs have been "offshored." Thus, 50% of full time american workers earn less than 25k per year. White christian men, of good morals are considered to be recipients of white, male privilege. Hence, they get little support from their government, big business and academia.
For a white catholic woman to have a large family, she needs to be able to rely on her husband for financial security, for herself and her children for decades to come. Given the situation for most men, that seems like an unrealistic goal for most women.
Therefore, it isn't surprising that most women are foregoing motherhood, in favor of a job.
If a woman is competitive enough to catch that minority of men who earn 50k per year or more and have proven that they've got the "stuff" to consistently beat the other men in competition for those kind of jobs, then she can settle down, have a family and stay at home and raise her kids in home school bliss. And, so long as she's frugal, they might live pretty well.
On the other hand, if a woman isn't competitive enough to "catch" that minority of men who earn 50k or above and have the "stuff" to beat most of the other men competing for another good job when the one he's got gets "offshored," then she'll have to settle for a guy who can't consistently compete his way into that top 25% of wage earners in america. In settling she'll have to accept a lifetime of financial insecurity. She may be faced with raising her children in poverty, which in america often means living in a high crime area, that is full of people who hate white people and can attack them with little to no consequences. She'll know that if her husband ever gives into/is seduced by the culture around him, she may have no way of collecting financial support from him, when he decides he doesn't want the responsibility of a family anymore, because the culture has taught him to be selfish and his flesh is inclined to be anyway!
So yeah, if she decides to have a large family and stay home and raise her kids, with a husband like that, then I think she is going above and beyond the call of duty and I'm inclined to think that is consistent with traditional catholic teaching.
