Part of the answer consists in the long, lingering impact of financial crises and deleveraging, well documented by Carmen Reinhart and Kenneth Rogoff in their book This Time is Different. At the same time, the financial imbalances and distortions that precede a crisis delay appropriate and necessary responses to technological and global market forces in the real economy as well.
部分原因在于金融危机和去杠杆化的长期而缓慢的影响。卡门·莱因哈特（Carmen Reinhart）和肯尼斯·罗格夫（Kenneth Rogoff）在《这次不一样》（This Time is Different）一书对此做了精到的描述。与此同时，危机爆发前所存在的金融不平衡和扭曲让应对实体经济中的技术和全球市场推动力的必要措施推迟了。简言之，经济和政策调整在以一种不可持续的方式进行，在一定程度上蒙蔽了人们的眼睛，让人们无法看到可持续的适应模式。
