Clear example of how the market fails the efficiency test: look at the trend in water bottles and aluminum cans getting taller and skinnier. Takes up more visual space on the shelf. Looks bigger and more substantial, but actually has less product inside. Takes more material and energy to produce. But the markup is larger = more profit! (also a PITA because tall skinny things have a tendency to fall over, but who cares). Producers are cynically anti-consumer and anti-efficiency, completely pro-profit.
