Answer:
During the 19th century, when women rarely worked, good education was hard for them. That's why they didn't get many jobs, either. So, they cooked and washed and watched over the children. This applies today, but differently. If women don't get jobs, then they usually have the role they had back in the 1800s. But, if they get a good education, which is more widely available, then they are way more likely to get jobs, and their role changes from housekeeper to provider and/or housekeeper.
