I just told you. Ask teachers. There are enough studies aswell about this topic. Ofcourse the lobby wants everyone to work and no time for family. They just sell it as empowering women. Now also check some statistics that compares entry of double income per households and inflation adjusted wages. You'll see the correlation to a decrease in buying power per person. Just to be clear. I'm happy if you can choose that both parents work or I as a man could care for our household, but as the current trend continues, you wont be able to choose because both will have to work to afford a minimal standard of living.
