I don't think he is denying the difference in kids, he is denying that we have any idea if that is an issue here. We just don't know what the issues are. I, for one agree with your assessment of kids. I also worked with them. However, the problem is that their environment is changing so fast, that people, and most of all the kids themselves are having trouble adjusting. I worked with kids who their environment was a cramped apartment with a huge tv set that mostly was in Spanish, because their parents were Hispanic. They were nice kids, just lived in a completely awful environment. For their parents, the environment was probably an improvement with what they grew up in.
