That's the wrong way to look at boom-bust cycles. The mistakes were made when investment unsustainably outstripped underlying value. You can feel bad in the bust times for those beneficiaries of the boom times, but they were simply paid forward for the bust years to come. That's just the economic sawtooth that will continue to happen as long as growth has insufficient pressure (regulatorily or culturally) for sustainability. It's all been seen before.
