Isn't this the lump of labor fallacy [1]?
I think the economic theory leads to a different description: As more women enter the workforce, the aggregate income goes up. Some of it is spent and becomes someone else's income. Some of it is saved in a bank which loans it out or invests it. The receiving business then spends it and once again the money becomes someone else's income.
IOW, as more people work, both aggregate demand and aggregate income rise. The economy shifts into a higher gear.
