I don't think it will be effective. The root cause is not PE, but human nature: greed, complacency, myopia, and etc. We can outlaw PE, but Boeing can simply invent another way to maximize their profit at the cost of product quality. It looks to me the only cure is to encourage competitors, so that long before Boeing becomes this rotting organization, their talented employees can join another competitor to beat the shit of Boeing. Unfortunately there's so much regulatory capture and intertwined interests between Boeing and governments that I don't think we will see any meaningful competition for years to come.
