This, too, runs counter to the economic mainstream. Free-market ideologues don’t want governments to think at all; and Keynesians want governments to think only about the short run, because they take to an extreme John Maynard Keynes’ famous quip, “In the long run we are all dead.”
简言之，政府需要事先学习和思考。这也与经济学主流背道而驰。自由市场思想家希望政府什么都不要想；凯恩斯主义者希望政府只思考短期，因为他们原因凯恩斯的著名评论，认为“长期看，我们都死了。”
