That's smart thinking. If you appear to be elitist, the other people in the trailer park will turn on you.
Wow, mention Bose and it really brings out the worst in people.
First of all, one of my best friends (and bandmates) lives in a trailer park. He's a genius musician who has dedicated his life and energy into the pursuit of his craft rather than selling out to some cheap capitalist model. Thus he lives in a trailer park. He's both humble and wise and obviously, not at all materialistic.
You should be ashamed, carlgo - this guy would give you the shirt off of his back and he sure as hell would never have the money for a really expensive set of headphones. But he's a master musician, not a pretentious audiophile, and he never seems to mind listening to music on less than ideal equipment. In fact, listening on standard fare audio equipment moves him in ways which you'll probably never understand.
I'm lucky to play music with him and even more lucky to call him my friend. You would look down on him for living in a trailer park, but he's a modern artist in every best sense of those words. I think he's better than elitist, materialistic lowlifes with fancy gadgets who troll around on forums trying to make people feel bad for their arguably poor choice in audio equipment.
And now I can see your defense - "I was just responding to bla bla bla..." Doesn't make it better. I don't know why trailer parks have become fair game when ethnic slurs are taboo. Do you really think it hurts less to be called poor white trash than to be called one of those other words? This is the product of a deranged society which worships money and looks down on people of lesser means. Of course trailer parks often have unsavory elements, but there are some real gems to be found there too. And of course much of the white trash of this world is rich. I know you didn't use the word "trash", but you were close enough to invoke a prejudice which is wearing thin.
