if the Nordic model was brought to these communities, the child income would start to decouple statistically from parent income. — boethius
We do, basically, share the same viewpoint. BUT, "IF the Nordic model was brought to these communities" is a very big IF, indeed. It's a big IF especially when the US seems to be disinvesting more than investing in education and quality-of-life programs.
There is a program in New York City called the Harlem Children Zone. One part of the program is to remediate one of the earliest appearing educational deficits that poor black children manifest--low verbal development. Poor black children (sorry, I don't have comparative stats for poor white children, say in Appalachia) hear about 20-30 million fewer words by the time they are 5 years old (I'm citing this from memory--it might be 4 years) than middle class white children. Further, they hear about twice as many command words (shut up, sit down, get out of the way) and about half as many positive phrases (good job, nice work, that's right!...) as middle class white children, same age.
If the deficit is not addressed early in life, it tends to result in life-long literacy deficits,
So the remediation program was directed to new mothers, or recent mothers in the project area. They were recruited on the street. The remediation consisted of coaching the mothers to talk to their children more, read to them, say more positive things, say fewer command words, and so on. Engage the child verbally, in other words. (TV has no effect here. It has to be caretaker to child.)
The results weren't magic, but they were very positive -- children in the program did better in school and for a longer period of time than children who were given remedial education once they got to first grade.
Naturally the program has not received generous support from the Dept. of Education (during several administrations). Surprisingly, the non-profit hasn't died of starvation, but I bet that it serves far fewer clients than it could with better funding.
That's just one small example. When you compare not-disadvantaged young children who are in excellent pre-school programs with ones that are at home, they tend to do better in social interaction, verbal skills, eye/hand coordination -- all that basic stuff. I don't have children, but I know parents who do have difficulty finding excellent, affordable day care and pre-school programs. I think France, for instance, does much better at this than we do.
Minnesota, where I live, is a lot like the Nordic countries in a number of ways. Our rate of gun deaths per 100,000 is about the same as Northwestern Europe. The state spends a lot on education and other pieces of public social infrastructure. At the same time that Minnesota schools rate close to the top, the gap between white students' and black (and other minority) students' performance is the largest in the country.
