There is something of a fallacy in your argument. Think about farm families, which used to actually make up a good fraction of our population. Mom may not have worked for a paying job, but she sure as heck worked on the farm.
Please, I’m not making a statement that women didn’t “work.” If you want to go back to more agrarian times, you’ll remember that families were also larger because people were a resource. Very young children had “jobs” to do around the farm too. I was referencing the result of massive employment of women which effectively allowed companies to keep down their labor costs through choices afforded from the expanded labor pool. The side benefit allowed higher productivity because in essence two people could be employed to do the job they formerly paid a single person to perform.
