I lived in a communist country in the 80s, but we weren’t happy either. Some things may have worked better than now, but many definitely didn’t. Of course there is a nostalgia factor, but it doesn’t count. So I’d call this bullshit and wouldn’t recommend it.

Until there is proof or external verification of the results, it’s just another case of Chinese propaganda.

I think that Diamanda Galas - The Litanies of Satan (or any other of her works) will be appropriate.
