Human societies can be broadly categorized into three groups:
1) The largest group (typically more than half) don't know what's going on.
2) The second group sees what's going on but doesn't do anything about it.
3) The third group (which is really tiny, like 1-in-10000) sees what's going on and does things, or they try to.
The open secret among groups 2 and 3 is that group 1 has to be managed (otherwise they go off the rails and crash civilization pretty quickly. It's happened before.)
So you get things like Religion, Sports, War, etc. all more-or-less to keep "the masses" on the tracks. The invention of the TV was a huge advance for this purpose. Suddenly people are staying inside and not causing trouble! You can even sort of program them: en mass people behave with statistical predictability. (E.g. you can get women to start smoking cigarettes. True example.)
Anyway, from this POV (I read "Manufacturing Consent" at a tender age) the masses have no agency. Democracy is a side-show, part of the management API for the masses.
What we're seeing now (from my POV) is the Internet ripping the lid off of the propaganda control system. "How Ya Gonna Keep 'em Down on the Farm (After They've Seen Paree)?"
