A lot of techies have lived in China and seen how that country has stronger social harmony than the West and is gradually outpacing it, so mass surveillance clearly isn't an obstacle to the general prosperity.
The problem with mass surveillance rollouts in the West is that they are incomplete: the cameras might go up, but not all infractions caught on camera are actually punished. Meanwhile, in China vandals and other disruptive people do get traced back to where they live and apprehended. I think that if such a vigorous policy were applied in other countries, even on a contrarian forum like this one you wouldn't see much opposition to the cameras.
