How exactly will focusing on those companies instead ensure that criticisms of capitalism are taken seriously?

Something something 'done away with', something something 'nine-tenths'.

some people in these circles have a way too delusional view of China for my liking, and will defend basically every part of it.

Which defenses have you found to be problematic in these supposed circles, enough to warrant the title of 'delusional'? Have you realized we're in a new cold war, with an increasing possibility of a hot war by the day? What need is there for any western leftist's unheard "nuance" in the current moment? You see people defending the PRC fiercely because they understand the stakes and rightly treat a dangerous moment with utmost seriousness.

Yeah, I wish it was better and I do think there are serious issues.

Why are you telling us this and not bringing your vague concerns to the CPC itself? What is the reason any western leftist even brings this up in the first place anyway?

It's a dream scenario. It did not exist and hence never died.

Why do you say rip?

I mean we live under capitalism right now and so our imaginations are understandably limited by what exists in society today. How would you see it then? I think the OP kinda sees humans being encouraged to take up a more generalist lifestyle instead of today's specialist lifestyle where people have careers and professions.

Maybe they're doing good work irl? I presume you live in the US? What have you heard about SAlt beyond them just being trots?
