Expecting media to keep up with the exact demographics of the USA when the rate of change is so drastic, is a pretty high bar.

They don't have to 'keep up with' it all the time though, is 'do your research' and 'maybe visit the place' for the show you're writing about 'a pretty high bar'?

(I'm not even sure I agree it's important to reflect, or at least not that it's always necessarily required, but I certainly don't think it being difficult is the reason not to, because I don't see how it is.)
