This excerpt is from an article on The Daily Caller:
Q: Is there a way to reclaim some of the values that we lost that you think are so fundamental to our exceptionalism?
A: That’s another way of asking whether America is capable of major cultural change. We know that the answer is yes. The Civil Rights Revolution is a good example. It went from a standing start in about 1954 to a national change of consciousness that enabled the Civil Rights Act of 1964 to pass just ten years later. The three (or four, depending on who’s counting) religious Great Awakenings are other examples. So it’s possible. I wouldn’t bet the ranch that one will happen.
