I don't know about the original commenter, but societies only work when the vast majority weigh the cost and benefit they derive from the status quo against the cost and potential benefit they incur by fighting against it, and decide that they're better off playing along.

Rightly or wrongly, we now have a situation where a lot of people believe that they no longer benefit from society, and are in fact harmed by it, while they also see a few benefit greatly. I believe this is why many people who understand the implication of that choice would still rather vote for Trump, who promises to break things, than for Harris, who would have only made minor changes.

This is not advocacy for anything. I think these people are perhaps not exactly wrong, but they don't correctly estimate the cost of breaking a democratic system, even a poorly working one.
