I am a parent, so not who you asked, but: I hard to gauge questions like this objectively when there are so many factors at play and the timeframe is ill defined.
I am unquestionably better off than single moms of my mother's generation. I don't face social stigma. I had a degree and strong work history under my belt and am able to earn more. The leadership of my company is more moms than not and our policies around absence, flex time, etc reflect that. That would have been much harder to find 40 years ago.
Schools are under strain but the standard of care is unquestionably higher for my son than for me. Teachers were brutal in my school. We were hit, shouted at, and humiliated. Several young women in my high school were sexually harassed or assaulted by teachers. Dropping out was common.
Daycare is far more expensive but also far less likely to kill, maim, or traumatize my child.
I am able to get treatment to alleviate for health conditions that my grandmother simply lived with. It's harder to get a GP appointment now in my hometown than it used to be, but the clinic is servicing far more patients and holding many more appointments than they were for my grandparents, even while the city population has not changed. So again, this is about increased standards (more visits with more doctors).
I think part of the reason things can feel very hard is that we are drowning in information. Our perceived standards are set by what is possible for anyone, anywhere-- not by what our neighbors or people known to us have. My classic example of this is my son, who was a late reader, can be disruptive in class, and isn't super great socially. In 1950, my dad was this kind of kid, and the standard response was essentially, "Welp, this one's kind of a dud. Punish him for misbehaving and put him on a vocational track!" And then to send him to juvy when he later made criminal levels of mischief. Whereas for my son, the response was a referral to a behavioral health clinic, counselling, a reading specialist, and a 504 plan. This is a far more complex, expensive, and labor-intensive outcome.
Edited to add: I'm sorry for the 1 million typos. I am dictating this into my phone while cooking soup with the other hand, and you're all just going to have to live with that.
