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.
Every system has tradeoffs, especially if compared to 40+ years ago. Depending on what was better and what was worse, that can easily be accounted for by the passage of time and building up of previous conditions.
