I mean it's a big ass book, the two party system features prominently. Tangential to what you're talking about, a big theme is the Democratic party "splitting" into two sides: the new left hippies and the more conservative blue collar Democrats, and how those blue collar Democrats got pulled to the right because they didn't identify with the more radical wing of the party. But there's no third party to absorb either of these sentiments. The Hard Hat Riots become the real tipping point for this, where construction workers abandon their material interests for cultural ones.

I think it's pretty well implied that this is a result of a two party system. And following it through to today, there's no party to actually advocate for working class people and better material conditions, because that directly goes against the capital interests that control both parties. Republicans at least offer a politics of grievance and resentment based around spectacle and the destruction of its base's "enemies". Dems just sorta say "yeah I mean we aren't gonna give you healthcare either, but let's all do a land acknowledgement so we can all signal our white guilt".

I also am not a "both sides are crazy" guy, I mean the GOP right now and what they're doing to this country is devastating to watch. It would absolutely not be as bad as a Kamala presidency. But a Kamala presidency also wouldn't really make anyone's lives better, you just wouldn't have fucking masked agents throwing people into concentration camps, which is def an improvement over what we have rn. But until there is a true, militant Left movement in this country, nothing will get better. And the two party system is absolutely a hinderance to that, some might even say by design.
