I see people say this all the time and it's simply not true. I was paying $18 a CD in college. I haven't payed more than $12 in years and most of the time it's about $10. When you factor in inflation, that gets even better. I found an online inflation calculator. It says from 86 to 06, that $18 went to $32.51. The calculator didn't go to 07 yet. So in 86 dollars, I'm paying 1/3rd the price I was paying for CDs 20 years ago.
I knew someone would try the "adjusted for inflation" argument sooner or later... the biggest problem I have with this argument is that the value of the todays dollar (terrible) and taking in consideration that the (inflation adjusted) average hourly wage has (since 1972) actually gone down, makes for twisted situation for buyer.
I am not a economics mastermind, nor am I employed in Tech (Art trades mostly) but I know that the 10 dollars an hour someone might make now,(don't condemn it too quickly, I would imagine that the majority of the target cd buying market is in payscale range, ie: high school college, post college) is much worse value to buy that CD than it was 15 years ago in 1992.
I think once you start figuring in the growing cost of living, the low dollar value, stagnant wage growth (in non tech areas) you might start to wonder why they dont come down in price.... although I just realized my own counterpoint - they could argue exactly this point for having not lowering any further... damn.
