Of the industrialized nations, the USA has some of the worst records when it comes to divorce, teen pregnancy, std infections, drug abuse, alcoholism, literacy, incarceration, violent crime, suicide, educational achievement, child mortality and life expectancy.
Our belief in free market capitalism led us to pour money into these problems, including prisons and the 'War on Drugs (TM)'. Per capita spending on education and healthcare is close to twice that of many other countries.
This investment has given us some of the highest paid teachers and doctors in the world, a bloated and inefficient managerial class, and legions of psychologists and lawyers to take care of the unhappiness and problems that result.
These problems are not new. Mark Twain wrote about the effects of over-nurturing parents in the 1870's, and Robert Heinlein discussed teen delinquency and bad mathematics education in the 1960's.
I used to visit my grandmother in Wiesbaden in the 1960's. She lived next to a lovely park. From four stories up and 1/2-mile away, we could tell which familes were US service personnel from the airbase. The German and African-American children stayed with their parents and behaved themselves. The other American children 'expressed themselves' by running into forbidden areas and making lots of noise.
That we have these problems in the poor urban areas is no surprise. That they occur as well in the suburbs is due, in my uneducated opinion, to an excess of wealth and free time, leading to a lack of competitive drive.
