There is definite discrimination, yet you'll find that there are a whole bunch who do enjoy it, as you may find a silent majority at certain places, for instance since they are commonly discriminated against they won't really make their opinions clear.
But ultimately, the main reason, I believe, for this is that, with modern technology you can just turn on your iPod and hear an orchestra, so in hearing classical music, it doesn't sound as 'cool'/epic as their music. Another contributing factor is the style of music, music portrays a message, always, whether, love, power, intensity, emotion, remorse, all these things are expressed in music, and the music a person listens to demonstrates some of their emotions. And at this point in time, few people feel like the piano can express their emotions, people want to be heard, people are depressed, when you think of depressed people listening to music, do you imagine them listening to classical, or rap something that requires no thinking, that in fact makes them stop thinking, why? because they don't want to face life. (this by the way, is not fact, this is theory, as I have seen it true in those around me)
