But you cannot argue that he aggressively pushed the interest rate below its natural level. Rather, Greenspan's mistake – if it was a mistake – was his failure to overrule the market and aggressively push the interest rate up above its natural rate, which would have deepened and prolonged the recession that started in 2001.
你可以提出格林斯潘在本世纪早期的政策是错误的，但你不能说他激进地将利率推到了自然水平之下。与其这样，不如说格林斯潘的错误在于（如果能被称为错误的话）他未能支配市场并激进地将利率推到其自然水平之上，那样做将会加深并延长自2001年开始的衰退过程。
