[Progressives of the 1930s] were determined that their vision of the managed economy should take precedence in all areas of life. Although they purported to have great sophistication on economic and social matters, their understanding of those matters was primitive, and their disdain for the evident signs of social improvement colored their vision of the success of the older order…. The Progressives and their modern defenders have to live with the stark truth that the noblest innovations of the Progressive Era were its greatest failures.
