Sarkozy is right that leverage is not necessarily good just because the free market allows it, and that speculators occasionally act in a destabilizing way. But speculators more often act as detectors of changes in economic fundamentals, or provide the signals that smooth transitory fluctuations.
但投机并非生而具有破坏性。萨科齐认为，并不能因为自由市场允许杠杆存在就认为它一定是好的，投机客的行为有时也会会造成不良后果，此言不差。但更多的时候，投机客通常是经济基本面的探测器，提供能熨平暂时性波动的信号。换句话说，投机客通常是稳定因素。
