I think you should read up on what Dengism actually is. You seem ignorant of it and the theory and intentions behind it.
I'm surprised it worked, in the sense that they were able to harness market economics and capital accumulation without turning into a capitalist dictatorship like happened in the West. Even with the benefit of hindsight, I'm not sure how they managed to avoid that (there is still time for it to happen though!) but I'm happy for their success.

Pretty much what most of the rest of the world has to say about it, I suppose.
