To those who think people are untitled to spend as much as they want on this stuff, I vehemently disagree: on a finite planet with finite and continually depleting resources, it is … shortsighted and selfish to spend insane amounts of dollars on audio gear.
No, what is shortsighted is to view human beings as nothing more than a tube through which food is consumed, and resources as mere matter. Our greatest resource is the human mind, and so the more humans the more resources.
What you think is scarce is in fact more readily available than ever. A thousand years ago all the copper, iron, gold, etc was buried in the ground. Now it is almost all dug up and refined.
Not that we need it so much any more, because there's that intelligence again, we have figured out much better more efficient ways of doing things. So for example there are more trees in N America today than in the 1800's because we are no longer cutting them down for heat and railroad tracks.
There's roughly a bazillion examples like that, but people don't know because the ones who are constantly running around predicting the end of the world are noisy and get all the press. Doom and gloom sells. Meanwhile productivity rises, poverty declines, and The End continues to be moved ever father off into the never-quite-gets-here future.
