I think that most of the smarter folks I know on the farther and farther left realize that a lot of what we see are "structural" issues, so voting (for establishment folks) stops being a real strategy at some point. In some sense, that philosophically materialist/idealist seems to be one tool for discerning the ideological differences between liberal capitalists and left anti-capitalists.

By contrast it's not surprising to me that as we go the other direction, the far right is less able to understand that these situations are structurally necessary for the operation of the systems that they support. Convincing those folks that it's not simply who is in charge is likely impossible. It will sound stupid, perhaps, but I have heard convincing arguments that the idea that systems are defined by "who is in charge of them" is fundamentally why "antisemitism" ends up being central to both the conspiracy folks and the fascists.
