Gesturing vaguely at everything is not an argument for anything. Supposing the person you’re talking to agrees that everything is bad, then it’s simply an argument for radicalism, not necessarily anticapitalism or whatever your particular strain of belief is. Someone could, while gesturing vaguely, just as easily argue that it’s because of moral decline, that society isn’t capitalist enough, for race realism, for the need for a strongman to take over, or really anything that’d promise (but almost certainly not deliver) to vaguely fix everything.

Quoting my reply to a similar sentiment: (link here: https://programming.dev/comment/1167202)

I’m really not trying to be a dick, but uhh… Look around? The world is literally on fire and efforts to put it out or even to stop pouring more gas on it are put down at every turn by capitalists in the never ending pursuit of more money for it’s own sake.

Well I mean it’s unclear to me that we’re much worse than previous points in history. I’d rather have the climate crisis over the nuclear one, or either of the world wars, or live under a feudal system where I’m owned by the local lord in his castle.

I sympathize (and agree) with the belief that the current system isn’t serving everyone, much less serving everyone equally. But the world is a complicated thing and we’ve got >7 billion people to feed! I think we should be very careful before deciding “yeah it’s time to tear down the existing systems and hope that there are better systems out there”. It’s easier to make things worse than to make things better.
