I'd say it's more the fake value that people are creating for such things, really.
I went along to a friend's own art exhibition once and stood listening to the local hipster pillocks trendies wittering and arguing something like how, "the artist is clearly expressing the zeitgeist of their relationship betwixt consumerist fetishism and recycling coture, possibly influenced by Lichtenstein or Machiavelli given the synergistic complex dialogue in the piece...", with their mates all debating, "No no, this is clearly the artist's ephemeral fascination with the dialectic of greed and the frantic, diverse practice of nihilism...". You know, the sort of pretentious arty farty BS that usually gets spouted by hipster wine-tasters on TV....
My friend had been listening from the side and basically cut in with, "Oh is that what I was doing? Wow, I thought I was just painting some pretty flowers...!!".
