Gregg, interesting article that puts things in a different perspective. Unfortunately for young kids even with a degree it is tough to get a start down that path with all the student debt and unemployment.
Another big factor is number and timing of children an staying married. A smaller family in a two parent home has the potential to give more resources and attention to each child. Watching my kids and their friends they are having smaller families, later in life and focusing on giving them educational advantages (and they aren't the 1% but maybe the top 25% or so). Contrast that with last week when I subbed in inner city schools while they were training the nurses in new forms they had to fill out for medicaid, and the poorer schools were full of kids with multiple siblings with different names, younger parents and one adult in the home (every single case I saw was a mother or grandmother), almost all free lunch and breakfast kids. What chance do they have of every being lifted out of poverty as compared to the parents I see in my neighborhood and my kids and their friends. Some of the kids I saw in Kindergarden and First grade knew less than my two year old grandchild and had no preparedness for learning to read and do basic math. Of course there are huge exceptions to this informal observation- but it does explain some of the gap between the poorest and richest in our society. Perhaps it is what the bottom percent is not doing right.
Needless to say I did this as a favor for a friends and it was a real eye opener to me, who normally sticks to suburban middle class and above schools.
You can tax the 1% at 80% and it won't be enough to overcome todays social issues.
