So back when being a stay at home mom was the norm, it was hard, but now that working moms are the norm, being a stay at home mom is easy? I don't think that checks out.
While being stay at home was the norm, around 33.9% of women in 1950 worked and it continued to go up. That is not completely negligible number. (The number for males was closer to 86.4%)
I think that things are hard for different reasons. Nothing will ever be easy. If you believe life will get to the point that it's easy, you've got things wrong.
