I've heard the postwar era described as a magical time when the economy was great, unions were strong, families were intact, taxes were reasonable, foreign relations excellent, good and evil clear, and so forth. Admittedly, this glosses over a fair bit (Hello, Dr. King...) but nostalgia is a powerful lens.
I begin to think the part we should miss most from that era is that the GOP was about actual, you know, politics.
