Exactly. Interesting piece by a former Amazon employee: http://www.eugenewei.com/blog/2012/11/28/amazon-and-margins http://www.eugenewei.com/blog/2012/11/28/amazon-and-margins "If you have bigger lungs than your competitor, all things being equal, force them to compete in a contest where oxygen is the crucial limiter. If your opponent can't swim, you make them compete in water. If they dislike the cold, set the contest in the winter, on a tundra. You can romanticize all of this by quoting Sun Tzu, but it's just common sense."
