. . . and the BHM generalizations and conjecturing continues. I really wish those who are not
parents would refrain before contributing unbased opinions on successfully raising children.
As a parent of twin 14 year old boys, I can honestly say it's not an easy job, nor something you're ever fully prepared for. However, being raised in a two-parent household, it at least gave me a foundation to start from. My parents admit to making mistakes raising us, just like their parents made mistakes raising them. All you can do, like all other achievements in life, is hope to do better than the previous generations.
The mistakes my parents did make, I made it a point not to make those same mistakes. For example, my parents didn't really say "I love you" very often. Therefore, I made and continue to make it a point to tell my sons I love you every chance I get. And even now, I make it a point to tell my parents I love them whenever I get the opportunity. Furthermore, I got my ass beat when I was kid and I didn't like the way it made me feel about myself. I vowed to never beat my kids, and I never have (of course they've been popped a time or two), but I try to raise them with positive reinforcement instead of negative reinforcement.
I think having both parents involved in a child's life is crucial, however single parent households can and do thrive as well with additional effort.
A lot of the children the OP are referring to are missing fundamental needs in the hierarchy of needs pyramid, and their parents likely never had those needs fulfilled either. It can be a detrimental cycle
