I can't speak to individual circumstances. I've certainly seen your situation and know that it happens. Just in aggregate though, children of two parent households overwhelmingly have better outcomes. In fact it's the single largest factor determining success in life, statistically. Certainly this can be in spite of, rather than because of your parents.
Also I probably mistakenly gave the impression that my mom cared. No. Her values were more that kids should be out of the house every day from breakfast until dinner. If she had left me to figure that out on my own in New York City I just would have been a kid on the street. As soon as I could get a permit to work and earn my own money was as soon as she stopped giving a shit.
I didn't get a higher education.
