The Deep State concept suggests that top-level individuals both inside and outside of government make a coordinated effort to influence government policy. Those individuals would typically be career civil servants at the highest levels, top-level financiers, and powerful industrialists. The Deep state isn't a shadowy conspiracy being mounted by the guys who issue drivers' licenses. Rather, it's an amorphous entity comprised of the most powerful individuals in society using that power to influence the things government does.

The first thing to ask is, why wouldn't such an entity exist? Society doesn't have a mechanism to ward off a Deep State. Quite the contrary. Powerful individuals are free to wield their influence- either alone or in concert and lawfully, of course- for their own interests.

If you scoff at the notion of a Deep State, then you believe that those with the most influence in society only use it charitably, and never in concert with one another. Doesn't that seem naive?
