Let us suppose three general rules as premises:
1) For any group of people, that group will be powerful in proportion as it is organised. A group of individuals, or smaller groups, acting in isolation from each other will be less able to exert much influence.
(This is why, for example, many of the most famous anti-colonial leaders were so keen on the idea of forming large federal organisations for their people – pan-Arabism, pan-Africanism, etc.)
2) For groups above a certain (perhaps variable) size threshold, acting in concert will require some co-ordination by some sort of representative organisations acting on behalf of the rest of the group’s members.
3) For any representative organisation acting on behalf of a smaller group, its tendency to act contrary to its members interests, to be ‘unaccountable’, will be inversely proportional to the independent strength of the individuals and smaller groups that it acts on behalf of.
