Katherine Mangu-Ward, writing in Reason magazine, looks at the results of Arthur C. Brooks's extraordinary book, Who Really Cares?
The people who give the least are the young, especially young liberals. Brooks writes that "young liberals—perhaps the most vocally dissatisfied political constituency in America today—are one of the least generous demographic groups out there. In 2004, self-described liberals younger than thirty belonged to one-third fewer organizations in their communities than young conservatives. In 2002, they were 12 percent less likely to give money to charities, and one-third less likely to give blood."
