Among rad-trads, there is a certain level of opposition to female education. Their idea is that women shouldn't go to college, young women should instead get married between the ages of, say, 16 and 21, and start popping out babies. FYI, canon law (Can. 1083 §1.) sets the minimum age for marriage for women at 14, minimum age of marriage for men at 16.
Now, I love babies more than pretty much anyone I know, but preventing women from getting an education will only get you a lot of dead babies (see here or here, for instance).
It is very well-known that the more educated the woman, the less likely her infants are to die (see here, for instance). High education among women greatly decreases infant mortality. Infants get sick, and when they do, you want an educated person there to take care of that baby. An uneducated mother won't have the skills necessary to prevent a baby from falling ill, properly assess a sick baby's needs, nor correctly handle the infant's illness. So, if you want those babies to live, you better educate their mothers: the more, the better.
But, as is also very well-known, educating women has a downside in reference to fertility. Not only does education take time - a woman in the classroom is, by definition, not at home taking care of children - the increased infant survival rate actually decreases family size and female fertility.
You see, when infant mortality is high (as it has been for nearly all of human history), parents have a lot of kids, because they don't know which ones will survive to adulthood. Family size is large, fertility rates are high because there are a lot of dead babies between the ages of one and five. But when infant mortality is low, parents stop having many children because they can be sure the few they have WILL survive to adulthood. They don't need the insurance policy of a large family. So, female education correlates to high infant survival. High infant survival correlates to low female fertility rates.
But therein lies the NEXT problem. All other things being equal, large family size is very well correlated with high numbers of priests and nuns. Small family size correlates to lower vocations to Holy Orders and religious vows. When fertility rates drop, the Catholic Church ends up with fewer priests and nuns. A LOT fewer priests and nuns.
So, the Catholic is caught betwixt and between. We certainly want low infant death rates, but we ALSO certainly want large family size so priestly vocations don't fall off. From a cultural perspective, nobody knows how to get both.
Many rad-trads don't understand how the correlations work, they just know that female education is somehow interfering with Catholic family life, thus the absurd and useless proposal that women shouldn't pursue an education. Ripping education out of women's hands is NOT a Catholic solution. When a solution is found, it will undoubtedly involve training up people who come from small families up to live as sacrificially as do those from large families.
That's a problem in how to educate parents, not a problem in how to prevent them from being educated. Anyone who advocates uneducated adults is advocating an essentially non-Catholic "solution", a "solution" that actually makes everything much, much worse.
