It’s all a matter of zeros. As I am retired, I think about net worth, but the same could be said about salary.
if an audiophile has a net worth of $1m, and has a system that he spent $10k on, it is no stretch to think that if he was worth $10m, he could easily have a $100k system, or if he was worth $50m, he could have a $500k system. And considering that the more money you have, your % of disposable income actually increases, that $50m guy could easily afford $750k speakers (and appropriate electronics) as easily as the $1m guy can spend $10k on his system.
I am not a wine guy, but this logic was used by a friend in reply to me pondering “who regularly drinks $1000 bottles of wine?”
