I think part of it is genuine naivety of the media, not being able to understand that there is ideology and theory on alternatives to the current dogshit system that goes back hundreds of years.

All they can comprehend is that the elected leaders and political thinkers can only have napkin-written bullet point talking points that end up making the system worse, and because of this history of fucking psychopathic neoliberals promising woke capitalism that ends up creating more concentrated wealth and worse conditions for everyone not a billionaire, that the better something sounds from a politician the worse it is going to be. Like, promising good things like social supports means that it's going to end up really really bad ultimately, and is probably somehow racist or antisemitic. So the only acceptable things are those that sound "realistic", which is a way of saying that the working class are being promised fuck all and the promise is that nothing will get better.

It comes down, at least partially, to fatigue with being lied to and being paid or beaten into submission.
