I thought of that when I read Kevin Drum's post on social trends in America. An excerpt:
Just about every social indicator you can think of has been moving in a good direction for the past couple of decades. Kids are better behaved. Crime is down. More people have access to health care. Divorce is down. Most indicators of racism are down. Income has risen considerably since the end of the Great Recession and is now significantly higher than it was when Bill Clinton took office. Etc.Kevin had started with a chart on the decline in divorces in the last 10 years, then segued into a discussion of why we don't realize all the improvements in the last 20 years. I agree with almost everything.
