There are a fair amount of younger people who also don't fool around with physical media in the traditional sense (digital objects being physical in another sense). $150 LP boxed sets are nothing new, but it seems like there should be a cheaper option. I also do not have a better-than-average income and have been collecting for over 25 years.
Then again, there are a lot more millionaires now than there were when I started collecting, and a lot more poor people who don't have time to think about $150 Mingus boxed sets as well.
