s constituted.

The more advanced the society, the more numerous and the more complex
are the relations between its component parts. The agricultural
inhabitants of the Ganges Delta have evolved a far more complex society
than that of the aborigines of Australia, but the civilization at the
mouth of the Ganges is simplicity itself compared with that of Britain,
Belgium or Japan. In the Ganges Delta each family group has a homestead.
Outside of the homestead, the community life is almost wholly
unspecialized. Even where the homesteads are clustered together there
are no stores, no recreation centres, and few churches or schools except
in the larger towns or in the market towns, of which there are a very
few, since only about one per cent of the people live in towns or
cities. Practically the entire population is occupied with the work of
the homestead, and the work of each homestead is very like the work of
every other homestead. ("The Economic Life of a Bengal District." J.C.
Jack. Oxford. Clarendon Press. 1916. pp. 1 to 40.)

How different is the French, German or Italian village, with its various
crafts, trades, professions, industries, recreation centres, schools,
churches and the like. Every such European community of three or four
thousand persons is in itself a complex society, while the industrial
city of fifty thousand people is a hive of related social activity.

The more highly specialized the group, the more complex, intricate and
precise are its workings.

This principle of social federation through specialization, association
and co-operation is nowhere better illustrated than in the case of the
present economic system. In each centre of population, in each town or
city, in each state, in each nation, in the world at large,--the
economic system is divided into various elemental economic groups or
units, falling under six main headings:

1. The extractive units, which are concerned with the taking of
wealth from nature's storehouse--the farm, the mine, the lumber camp.

2. The fabricating units, which are busy changing the products of
farm, mine and lumber-camp into semi-finished or finished forms--the
mill, the smelter, the factory.

3. The transportation units, which carry goods or people or messages
from place to place--railroads, ships, trucks, telephones.

4. The merchandising units, which assemble the goods turned out by
the fabricators and distribute them to the user
