Literally any mass protest in the US gets confronted by militarized riot cops, unless they're neo-Nazis in which case the cops tend to protect them. Police forces in the US are donated equipment directly from the military, up and to including tanks. Look up the Standing Rock protests or the murders of Ferguson protest leaders for an example of how that escalates even further if the protestors aren't majority white.
Of course, that's what happens when the system fails to keep obedience. Mass media conglomeration in the US allows easy control over what is and is not reported, and how. All the major media corporations have admitted to cooperation with the security state in one form or another, and don't speak on things that might "threaten national security". But even that much is manufactured to the extent that it's a light touch - the ideology of the media is so fervently pro-US that they don't need to be told 90% of the time what to do, and regardless those with stake in the government and stake in the media are often synonymous. Obviously they have little desire to report against their own interests.
If everyone hates NSA monitoring, why does it continue? You're allowed to hate it, you're just not allowed to stop it. That is a dimension of consent manufacturing, and in fact one that China uses as well. Bitch and moan all you like, but stay off the street. Something I like to say is that the big reason we can't repeal the Patriot Act is that we never enacted the Patriot Act - its passage was with small debate and smaller dissent, an act of power rousing to move openly. Of course, true acts of state power have consequences, and so are kept to the minimum necessary.
The truth of the matter is that the Chinese government is just somewhat less elegant with consent manufacturing...or are they? How would you know, seeing as what you know about China is sieved through the US media apparatus before you learn it?
