—Jimmy Carter (James Earl Carter, Jr.)
“More than a decade after our fellow citizens began bedding down on the sidewalks, their problems continue to seem so intractable that we have begun to do psychologically what government has been incapable of doing programmatically. We bring the numbers down—not by solving the problem, but by deciding it’s their own damn fault.”
—Anna Quindlen (b. 1952)
“The problems of all of humanity can only be solved by all of humanity.”
—Friedrich Dürrenmatt (1921–1990)
