What a lovely innuendo.
They might be "hungry" for these details, but not because they envy the lifestyle or are looking up to it. A lot of Russians still view Americans as self-indulgent, somewhat retarded know-it-alls, bathing in life's luxuries that make no sense. There are stand-up comedy acts that center on how you can't get a whole pickled cucumber in McDonalds (even though there's a sliced version in every hamburger), how there exist separate trimmers for a nose and for an ear hair, how Americans drink vodka "on the rocks", etc. Ordinary Russians are no more hungry for the lifestyle details than for UFO encounter stories and Thai transvestite pictures, with "hungry" being way too strong of the word in either case.
