In the best case – without a sharp decline in financial assets accelerating an economic downturn, a sudden collapse of a defective growth model, or even rapid increases in liabilities associated with demographic shifts or health-care technology – it might make sense to focus only on controlling liabilities. But a best-case scenario provides a poor policy framework in our imperfect world.
最好的情况是——金融资产不会急剧下挫而导致经济衰退加速，有缺陷的增长模型不会突然崩溃，或是与人口结构转换或医疗技术相关的负债不会急剧上升——这样仅仅集中精力控制负债就说得通。然而这种美梦式的设想会给我们这个从不完美的世界带来差劲的政策。
