穆罕默德·艾利安（Mohamed El-Erian）指出，人们没有从2007年金融危机汲取的教训是，当前的经济增长模式“过于依赖流动性和杠杆 — — 先是来自私营金融机构，然后来自央行 ” 。
According to Mohamed El-Erian, the lost lesson of the 2007 financial crisis is that current economic-growth models are “overly reliant on liquidity and leverage – from private financial institutions, and then from central banks.”
