Maybe both parents had to work two jobs. Maybe they had their own life challenges.

Perfect parenting, if such a thing exists, certainly has an economic minimum price.

And likely has a previous generation upraising requirement as well. There's a reason maladaptive cycles continuing down through generations happens: parents are often defined by their parents ad infinitum.

What matters as a parent is being the best you can be, and striving to be better than your parents were.

The obvious example is what if they were simply too much for the parents even with adaptation. Though, not sure if I'd believe that.
