American businesses have postponed much-needed capital spending and, with American airports and bridges in appalling condition by developed-country standards, investment in infrastructure is crucial as well. Indeed, it is very likely that reviving growth will lead to larger current-account deficits, even if the savings rate improves and domestic energy production curtails oil and gas imports.
未来美国经济的复苏几乎必定将触发投资活动的重新抬头。美国企业延迟了急需的资本支出，此外，考虑到美国的机场和桥梁用发达国家标准衡量不可不谓破旧，因此基础设施投资也很关键。事实上，增长复苏极有可能导致更大的经常项目赤字，即便储蓄率有所改善、国内能源产量增加减少石油和天然气进口。
