QUOTE : It’s hard to know how to live for a country that regularly tears itself apart along every possible ethnic and demographic boundary. The income gap between rich and poor continues to widen, many people live in racially segregated communities, the elderly are mostly sequestered from public life, and rampage shootings happen so regularly that they only remain in the news cycle for a day or two. To make matters worse, politicians occasionally accuse rivals of deliberately trying to harm their own country—a charge so destructive to group unity that most past societies would probably have just punished it as a form of treason.
