Re: 2, I'm actually responding to this point in the parent, which says the source of the next generation of NSA recruitment pool is: talk-radio fear mongers who continually generate a stream of xenophobic, america-fuck-yeah types who will happily spy on their countrymen. You may be able to see how I connected the dots to Fox News.
I will connect them further. Fox News has an aging viewership for many reasons. Watching talking heads, as a model of receiving information about the world, is on the way out. Fox has committed to ideologies that, for one reason or another, are not believed by young people. In parallel to the changes to work noted by Stross, there are changes to media consumption that are also driving younger generations farther from the baby boom culture.
