The dominance of Friedman’s ideas at the beginning of the Great Recession has less to do with the evidence supporting them than with the fact that the science of economics is all too often tainted by politics. In this case, the contamination was so bad that policymakers were unwilling to go beyond Friedman and apply Keynesian and Minskyite policies on a large enough scale to address the problems that the Great Recession presented.
弗里德曼的思想在大衰退开始时占据上风，这与其说是靠证据支持，不如说是因为经济科学常常被政治左右这一事实。在这一例子中，政治的染指非常严重，以至于决策者不愿超越弗里德曼的范围、大规模地应用凯恩斯主义和明斯基主义政策解决大衰退所暴露的问题。
