I have triangles on the mind lately. I used to think that economic activity was a triangle with growth, competition and distribution making up its three sides. The perfect triangle is equilateral. That is to say, its three sides are identical in length.

It would then follow that economic activity has reached perfection when its three elements of growth, competition and distribution coexist with identical force. Things start to go wrong when the three sides of the economic triangle lose their identity. Too much growth. Too much competition. Too much distribution. In each case, perfection is destroyed.

That image still holds, but I now feel there are other ways of defining the three sides of the economic triangle. They could be thought of as people, goods and money. Alternatively, they could be defined as global, national and local. In both cases, the law of perfection applies: The three sides must be identical in length for perfection to reign.
