The social science backs up common sense and observation concerning the terrible social policy of encouraging women to work outside the home rather than marry and raise children.
Whatever the theoretical benefits of doubling the percentage of women in the workforce were, the material costs to society have dramatically exceeded them. This is not about women working per se, as one-third of women have always worked, but the change since 1950 is that most young marriage-age women now work so that old men can collect Social Security, watch TV, and play golf instead of working as they always had before.
The results have been not merely dyscivic and dysgenic, but downright dyscivilizational. And regardless of what you think on the matter, it is clear that a society which encourages widespread female education and employment is not sustainable and is guaranteed to collapse sooner rather than later.
