In general, an engine under higher load will run more efficiently. I do agree that there is a balance to be struck.

Sure, you can go with more aggressive gearing, but high sustained revs eventually kill engines, or at the very least wear them out prematurely. And gearing also has a negative impact on fuel economy. Practically all performance cars that make peak power at high rpm get poor fuel economy. Some of this is internal engine friction, some of it is gearing, some of it is simply not caring. But when a 2.2L I4 in a sub 3000 lb car gets nearly about the same fuel economy of a 6.2L Corvette, there is something seriously wrong.
