The lesson is that politics and economics are inseparable. Markets on their own may be neither efficient nor stable, but the politics of deregulation gave scope to unprecedented excesses that led to asset bubbles and the rolling crisis that has followed their collapse.
得到的教训就是政治与经济密不可分。市场本身既不有效也不稳定，但是撤销管制的政治行为为前所未有的过剩留出了余地，从而引起资产泡沫和泡沫破裂后的滚动危机。
