Why do you assume only you can see that’s it’s propaganda and they can’t?
In the same way, I have no doubt that many citizens of the USSR or China or Nazi Germany or even the US can see through the propaganda targeted at them. But I don't think anyone would argue with the idea that propaganda was and continues to be effective for a significant (and important) portion of the population.
I would also think that, say, a historian who is an expert on propaganda, or an economist who is an expert on labour relations, a political campaign manager, or a company marketing manager would be able to more accurately and quickly identify propaganda when they see it. Some people can see through certain propaganda. That's not controversial.
I find Amazon worker susceptibility to propaganda to be a little silly. And I'm talking about "fake news" propaganda, not promotion of a true, but pro-Amazon viewpoint.
Most folks I worked with a lower-paying, manual labor jobs had zero illusions about their employer. They aren't getting the "bring your whole self to work" and "help us change the world" bullshit that the big companies feed their white collar workers. It was very clear that the employer looked out for themselves (e.g. profit) and workers were easily replaceable.
I think people who claim they were manipulated need to give the workers a little more credit.
And I think anyone should point that out - whether it's a union organizer in Alabama, a tech worker making 10x the salary (who, by the way, may also have an interest in improving cultural support for unions if they are a tech worker in favour of software engineer unions) or a historian on capital-labour relations. As far as I know, however, no tech worker has contacted anyone in Alabama and told them they're brainwashed.
'Paternalism' would be someone pushing the ballot for them 'for their own interests'. That does not preclude discussion of priorities, rationality, and the rational frameworks (epistemological/ideological/moral/practical/etc.) we have available to discuss how wise those decisions are.
