+70. Group interests and folkways.+ Whenever a group has a group purpose that purpose produces group interests, and those interests overrule individual interests in the development of folkways. A group might adopt a pacific and industrial purpose, but historical cases of this kind are very few. It used to be asserted that the United States had as its great social purpose to create a social environment which should favor that development of the illiterate and unskilled classes into an independent status for which the economic conditions of a new country give opportunity, and it was asserted that nothing could cause a variation from this policy, which was said to be secured in the political institutions and political ideas of the people. Within a few years the United States has been affected by an ambition to be a world power. (A world power is a state which expects to have a share in the settlement of every clash of interests and collision of state policies which occurs anywhere on the globe.) There is no reason to wonder at this action of a democracy, for a democracy is sure to resent any suggestion that it is limited in its functions, as compared with other political forms. At the same time that the United States has moved towards the character of a world power it has become militant. Other states in the past which have had group purposes have been militant. Even when they arrived at commerce and industry they have pursued policies which involved them in war (Venice, Hansa, Holland). Since the group interests override the individual interests, the selection and determination of group purposes is a function of the greatest importance and an act of the greatest effect on individual welfare. The interests of the society or nation furnish an easy phrase, but such phrases are to be regarded with suspicion. Such interests are apt to be the interests of a ruling clique which the rest are to be compelled to serve. On the other hand, a really great and intelligent group purpose, founded on correct knowledge and really sound judgment, can infuse into the mores a vigor and consistent character which will reach every individual with educative effect. The essential condition is that the group purpose shall be "founded on correct knowledge and really sound judgment." The interests must be real, and they must be interests of the whole, and the judgment as to means of satisfying them must be correct.
