Why is prog rock always called "snooty"?

I thought the real reason why punk rockers rejected prog and classic rock in general was because of its irrelevancy to their lives, and this is a valid criticism. After all, if one has lost their job from a factory and struggling to put food on the table, then a song about an armadillo-tank hybrid born from the eruption of a volcano, vanquishing over a variety of fictitious creatures until finally being defeated by a manticore, will seem quite unimportant to them. And when rich rock stars sing about the concerns of ordinary folk, it can seen quite phony, as if they are using the plights of the poor to get richer.

In a recent poll, hip-pop was the most disliked music by members of this forum. Why? Could it be that to middle-aged white men living in the suburbs, the stories of black urban youth are irrelevant?

It is interesting to note that Van der Graaf Generator managed to avoid the scorn given to other prog rockers. Could that be because Peter Hammill tends to write about the human condition, and thus maintain relevancy to those who reject other prog? And because Van der Graaf Generator were never really big, they also avoided being seen as phony.
