Collectivism holds that the individual has no rights, that his life and work belong to the group (to "society," to the tribe, the state, the nation) and that the group may sacrifice him at its own whim to its own interests. The only way to implement a doctrine of that kind is by means of brute force - and statism has always been the poltical corollary of collectivism.
