Rich Lowry, editor of National Review, has written a very interesting piece about this phenomenon. He begins by saying:
The unemployment rate for people with a college degree or higher is 5 percent. If that were the rate for everyone, it’d be the 1990s again. But college graduates are only 30 percent of the country. For the rest of the population, the jobs picture is grimmer. For people without a high-school degree, the unemployment rate is more than 15 percent. If that were the rate for everyone, it’d be the 1930s again.Employment level isn't the only difference between the educated and the rest:
The highly educated (with a college diploma or higher) are less likely to divorce, less likely to have children out of wedlock, and less likely to commit adultery than the moderately educated (high-school degree or some college) and the least-educated (no high-school diploma).Therefore the children of the educated are more likely to succeed, etc. I recommend the entire article to you; much of it is based on research by Bradford Wilcox of the National Marriage Project at the University of Virginia, which can be viewed here.
