Most economists agree that underinvesting in infrastructure is economically unwise and fiscally irresponsible. In a 2013 survey of economists by the University of Chicago, 75% of the respondents agreed that, “because the US has underspent on new projects, maintenance, or both, the federal government has an opportunity to increase average incomes by spending more on roads, bridges, railways, and airports.”
大部分经济学家都同意，基础设施投资不足在经济上不明智，在财政上不负责。在2013年芝加哥大学经济学家调查中，75%的回应者认为“由于美国在新项目或维护上的支出不足，或两者兼而有之，联邦政府有机会通过增加道路、桥梁、铁路和机场支出提高平均收入。”
