All this means is that the US has managed to achieve a propaganda state without the explicit threat of force...
Do you recall when GWB took office and long time members of the press core were kicked out if they asked tough questions?
This happens all the time which is why you don't find certain stories/angles covered in the mainstream press.
Consider that Tim Russert was considered the most hard nosed journalist because he had the gumption to ask a tough question or two... usually all he did was quote a few things the person had said in the past and ask them to explain their current claims (which usually turned their faces quite red). If this is hard nosed journalism we're all in deep trouble.
Most news today is full of stories that make Americans feel morally superior... stories about how women are mistreated in all sorts of other countries... how politicians are corrupt, and how the economic opportunity stinks (elsewhere).
There is also tremendous deference paid to titles and institutions in the US that should not be -- and would not be paid to titles and institutions of another country.
Why, for example, should we take the term "Chairman of the Federal Reserve" seriously, but take some other country's "Minister of Economic Affairs" less seriously?
All this is part of a media whose purpose is to help Americans feel that they have the moral high ground so that wars can be waged whenever necessary. The media doesn't have to overtly support a war -- in fact it is expected to question it (but by asking the wrong questions).
There are a lot of things you decide not to say/think if you expect to be on a national TV show, quoted in a national paper, be appointed to a cabinet post, etc. Why the voluntary censorship? Because all that stuff is such a downer. Why worry about it when we can just order another burger and get free healthcare and feel good about our google searches because google is taking a stand against horrible china. Why would anyone fight these memes when they make everyone so happy?
In the US the entrenched interests have been so successful, in fact, that we see all of this as perfectly normal and reasonable.... and, of course, we amplify differences with another country (like China) out of moral superiority and righteous indignation... Nothing makes us feel better than feeling sorrry for some poor victim of a propagandizing state, after all.
This isn't a conspiracy (or a conspiracy theory) it's just what you get when entrenched interests flourish in a stable, prosperous country.
