Having both parents work is a personal choice. Before my Wife and I had children, we learned about a situation with a relative where her daughter thought she had two moms and the one during the day was nicer than the one during the evenings. The daughter had an unhealthy relationship with the sitter, and it went both ways. The sitter would go out of her way to do things for the relative so she could keep caring for the girl.People need to work and finding large numbers of sitters now will be almost impossible.
After hearing that, my Wife and I decided that one of us would stay home when we had children so they'd have our values and learn to do things from us. Since I had the higher paying job with more potential for advancement, she stayed home. She never worked for pay after that and was able to fully participate in school and extracurricular activities of our kids. It was better that way because I was orphaned as a teen and didn't know how to be very nurturing because I never experienced much of that in my childhood.
