Are you talking specifically about single mothers in the black community or in general? I was raised by a single mother in the 80s when divorce was uncommon and despite some speed bumps, my brother and I have both persevered and become contributory members of society.
Were you raised in the inner city surrounded by gangs, drugs and joblessness?
Dr. Ben Carson was raised by a single mother who was totally illiterate but recognized the importance of education for her kids. Unfortunately, people like that are the exception rather than the norm.
I'm a huge fan of African wildlife...I've been there several times and own every available National Geographic/BBC bluray on the subject.Some time ago I tuned into an Africa documentary that was focusing on a problem a South African national park was having with juvenile..."teenage"...male elephants.These teenagers were going wild...attacking other animals and causing huge problems in the park.It was decided that the problem was a lack of adult males to be teachers/role models/disciplinarians.That shortage had been caused by poachers...adult males are most targeted by poachers because their tusks are bigger and more valuable.
So they decided to "import" adult males from other parks.Not too long after that project was complete the "teenage" males were back to normal behavior.
IMO it works the same...almost always...with human males.
