Head out on a tour of the castles of medieval Europe and you'll quickly catch on to a castle's three key features. What you see first is the bailey—a large area surrounded by a substantial wall where most of the population lived and most of the life of the community was conducted.
In 2011, the wealthiest Americans—those in the top 20 percent of earnings—gave only 1.3 percent of their earnings to charity. Those in the bottom 20 percent donated 3.2 percent of their income. Several theories exist as to why the wealthy are inclined to give less: by their very nature they are driven to look out for their own interests, and they are less likely to be exposed to real human need. Wealthy people tend to give to institutions from which they benefit, such as universities, museums, and arts organizations, while the poor tend to give to social service charities and religious organizations (Atlantic, March 20).
