>We are always wary of guiding for mean reversion. But, if we are wrong and high margins manage to endure for the next few years (particularly when global demand growth is below trend), there are broader questions to be asked about the efficacy of capitalism.

I find this title to be misleading. The above quote can be paraphrased as, "We think profit margins will revert to the mean. If they don't, we will be really surprised that capitalism isn't working as we think it should."
