Consider that the machinery to make group decisions and allocate resources already exists (laws, institutions, government, etc). It is imperfect and can be improved. But what is relevant here is that groups of people wish to alter the machinery in certain fixed (uncreative) ways. The unconscious motive is that of preserving their own identities.

An extreme case would be a Dr Evil figure who will not examine his own heart and needs the world to burn just so he can pretend to himself that he's a good person. So he makes the world burn. At every stage convinced of his own righteousness.

This explains why 'war is the continuation of politics by other means'. What passes for peace is trench warfare where the only progress is sideways. Improving the machinery may be desirable but in practice politics is dominated by preventing inevitable perturbations from escalating into open hatred and violence.

(More parochially one can tell when politics is influencing the discussion because there is always blaming going on.)

In modern vernacular it seems that that sense might be better expressed as "policy", rather than "politics".

Politics is the process to decide upon the policy.
