Describing the modern state of things as merely 'capitalism' or 'late stage capitalism' is really not that helpful. You can afford to choose a more specific term or be more descriptive. Like obviously there are issues with Capitalism generally, people make careers off of describing that. But maybe it is more useful to target the actual status-quo rather than its unrealized or only partially reified platonic ideal? Or going the socialist variant of apocalyptic about it?

Or maybe it is not only worth talking in terms of further specifics, but also talking about something more general than 'capitalism', since unlike what a bunch of brocialists think we've got a number of mostly unrelated problems.

Something about just ranting about 'capitalism' is neither specific enough nor general enough when you are defining what is so oppressive about life on earth now.
