"Tracked" is a bit much, for good and bad. There are potential benefits to prolific tracking, but there has to be a system of integration to realize them, which is totally lacking. In Shenzhen, if someone steals your wallet, the police can collect camera data from all sorts of sources around the time and place and track the thief down, and you have a reasonable expectation of getting your property back. In random US city, even if there are likely many cameras that could provide similar tracking capabilities, police will just shrug. So we don't even get any of the theoretical benefits to all this surveillance, all we're left with is random abuse.
