Yet, for the most part, limited cooperation has been the world’s chosen course in recent years, with countries believing not only that they must fend for themselves, but also that their debt levels impose a hard constraint on growth-generating investment. The resulting underinvestment and depreciation of the global economy’s asset base are suppressing productivity growth and thus undermining sustainable recoveries.
但是，近几年来，在绝大部分情况下，世界的合作相当有限，各国不但认为必须做好自我保护，还认为它们的债务水平构成了对刺激增长的投资的硬约束。由此导致的投资不足和全球经济资产基础的折旧正在遏制生产率增长，从而破坏可持续复苏。
