Yup. The norm should be single income households. With how expensive daycare is these days if your wife is not in a high paying field her income just goes toward daycare anyways. it It also makes for happier families, stronger bond between husband and wife, and everyone feeling more fulfilled.
Every woman I know who became a stay at home mom, even with the loss of income, were much happier and more fulfilled than going to a cubicle and sitting behind a keyboard 5 times a week. Although, every woman, including my family, I know are traditional, no “screen time”, etc. So I’m speaking from personal perspective.
