I have Anderson on and he just said that 70% of mothers today say that their lives are more stressful than their mothers.

In general, it might be true because things are harder in general these days. For example, it's so much more difficult to survive on on income than it used to be, people work more hours on average, everything is crazy expensive, and our homes are worth half what we paid.
For me though, it's not true. My parents had a miserable marriage that ended when I was 5 years old. Then my mother was single, then married a loser. All of her choices were bad ones, and that's on her, but her life was not a happy one.
I have been a stay at home mom from the beginning, I have a happy marriage, my husband is easy going, funny, and very helpful with the house and kids. He's made it to every karate practice, both the kids' and ours. He's loving and supportive, and that makes life easier. We moved to a city we like, and if there's something in our lives that don't work, we make the choice to change it. My mother never did that.
