You are totally wrong. Unless you are a high-profile figure, you have a much much better chance to have privacy in China than in the US. The US NSA is much much more capable than the Chinese one, they are as immoral as each other, and as willing to invade everyone's privacy as each other.
I am not going to discuss whether I am wrong or not. Let's not fool ourselves. You do not honestly think anything is really private anymore? In either China or the US or anywhere else for that matter. We would have to live in a perfectly closed bubble without communication for that to happen.
