It would be about control. Like slavery. The women would work and nominally be paid for their effort, but deemed too foolish to spend or invest it properly, so a man in the heirarchy would be put in control of capital. The capitalists are enamored with systemuc low risk profits, because social progress has destabalized their soft power base.

Slavery is where this moralism is headed. Because labor is such an annoying cost, why not minimize it.
