A question about changing societies?

How can society achieve coherence and stability when the customary ociations and attachments that had characterized village life have been ruthlessly dissolved by the rapidly developing industrial-urban-capitalist order and when religion no longer unites people? Were 20th century dictatorships responses to the dilemmas of modern society yzed by social theorists like Freud who argued that man could not be regulated without civilization doing its utmost efforts to set limits to man's aggressive instricts?
