This conversation is now a day old. Given current levels of attention spans, I am not sure that a response at this time would be useful, but nonetheless, you are right and I do owe you one.
First, I should point out that I speak from experience: I have been one of those poor children and have known many of them. I have experienced not having enough to eat and attended poor schools. Fortunately for me, these experiences were relatively short lived. However, because of those experiences, I retain a keen interest in the state of poverty, poor people, and how they live. Now, on to your points.
> Having little to eat and poor schools do not keep a child from learning from others. There is ready access to the internet through libraries in the U.S. with a wealth of information online, and a lot of books on the shelves there also.
Obviously there are exceptions, but most poor schools do not have internet access for the students or computers for them. If they do have a library, it is generally inadequate and most are not encouraged to use it. The greater problem, however, is the issue of hunger; it is very hard to concentrate or develop one's self in a hungry state. Adults can, and do learn, to deal with the state of hunger but children do not. A hungry child is only interested in one thing and when the state of hunger persists, will adapt, however they must, to a life of hunger. That generally means they will make what we would consider poor choices.
> If you take away all genetic factors (tendency towards aggression, lower intellectual capacity, etc.)
Tarring poor people (or any other sort, for that matter) with some sort of genetic failing is a convenient way to explain why they are less successful than you are, but unfortunately sidesteps a whole set of other reasons (historical, social, political, geographic) than generally has a far greater impact on one's life than genes. I was born in Africa and was lucky enough to have parents who eventually ended up in the United States where I availed myself of the opportunities, etc. I am proud of my intellect and have achieved much because of it, but I would never claim that I succeeded merely because of it. I have met many smart people who were simply not as lucky as I have been to make that claim.
> and environmental factors (is the child worried about being shot, peer pressure to join a gang or get into drugs or alcohol, etc.), then in the end it is more about parenting and community, not about poverty.
Here, the combination of factors listed seem to point to an urban American child. Problem is, there are many poor children in other countries who do not face these same pressures and yet, still have the same outcomes.
Parenting helps a lot. Community helps a lot. But if the lack of them were the problem, we'd see far less poverty than we do.
I'm afraid I've gone on for too long and will have lost some readers, but I hope this better explains my earlier posting and why I claimed that you did not speak from a knowledgeable position.
