Kevin Drum had a recent blog post on how incarceration rates are down among younger people and up in older populations and the links between this and lead.
This led me to thinking about how a lot of the problems of the last 30 years are commonly attributed to many of the same characteristics that are often associated with criminality such as selfishness and a short term orientation. Since behavior is highly associated with social context, it stands to reason that these traits would be expressed differently in people with higher socioeconomic status then the low status people that are often incarcerated for crimes.
If this association does exist it would help to explain how our society shifted away from the more communal values of the 1950s and 60s when business and government were both moving towards a more inclusive vision that engaged diverse stakeholders* to the time since the 1980s when ideas such as shareholder capitalism began to take hold and dominate public discourse. Today the upper reaches of business and government are dominated by people who are in the age groups that are being associated with higher crime and incarceration rates. If there is an association between lead and criminality in people of low socioeconomic status it would hold to reason that there is a similar influence on people of higher status, perhaps helping to explain some of the extremely short term thinking that has become common on issues like the environment and inequality among people of high status.
*limited of course by holdovers of earlier inegalitarian social relationships and the prejudices of the time, but these were times of progress rather than regress
