Stall speed is a terrifying risk for an economy like that of the US, which desperately needs to grow robustly. Without rapid growth, there is no way to reverse persistently high and increasingly structural (and therefore protracted) unemployment; safely de-leverage over-indebted balance sheets; and prevent already-disturbing income and wealth inequalities from growing worse.
失速对于像美国这样的极度需要稳健增长的经济体来说具有很高风险。没有快速增长就无法逆转持续且越来越倒向结构性（从而会更加难以根除）的事业趋势，无法实现过度负债的资产负债表的安全去杠杆化，无法防止已然恶化的收入和财富不平等雪上加霜。
