Buchanan, along with Milton Friedman and many others, correctly pointed out that government failures are as numerous as market failures. So, even in areas like infrastructure or education, it is necessary to compare the benefits and costs of the imperfect fiscal and regulatory policies likely to be implemented by fallible, self-interested officials with potentially imperfect market outcomes.
布坎南和米尔顿·弗里德曼等许多人正确地指出，政府和市场一样经常失灵。因此，即使在基础设施和教育等领域，也有必要比较不完美财政和监管政策的收益和成本，有私利在其中的不可靠官员可能实施不完美政策，造成潜在的不完美市场结果。
