Why Don't More People Love Audio?

Can anyone explain why high end audio seems to be forever stuck as a cottage industry? Why do my rich friends who absolutely have to have the BEST of everything and wouldn't be caught dead without expensive clothes, watch, car, home, furniture etc. settle for cheap mass produced components stuck away in a closet somewhere? I can hardly afford to go out to dinner, but I wouldn't dream of spending any less on audio or music.
I think basically because we are true music lovers, it doesn't matter if anyone ever hear, or see your system. People that drives flashy cars, wears expensive clothing not all, but some, do it for the show.
Given the lack of fidelity in many, or even most, pop music today, high fidelity probably worsens the experience of listening. Also, so many other ways to spend your leisure hours are now available.

It matters little to me as my grandchildren do appreciate high fidelity and have taken up musical instruments.
Why don't more people know the difference between freshly picked peaches, blueberries, rasberries, strawberries and grocery store bought. They just don't know any better.

A foodaphile knows there's a difference in taste and flaver between green, red, and yellow bell peppers. Not everyone does. Audiophiles are the same except with audio equipment.

Best peaches in the world grow right here in Palisade, Co. There's a local pride in this, of course, but this does not make it impossible to sell canned peaches in metal vessels and sugary syrup in out supermarkets. Some people actually prefer their peaches that way. I'm reminded of Americans who travel to Paris and choose to eat at McDonalds. Why in hell would they not want to experience the exquisite cuisine for which the French are world famous and which they cannot duplicate back home. I'll never understand. There's no accounting for taste.
That said, it is likewise important for audiophiles to realize that what they have found in their hobby is tantamount to religion and, as such, is personal. Not everybody finds salvation in the same book. I live in Colorado and don't ski. To many that is like ignoring French cuisine when in Paris. Whatever! I love it here but I'm not much given to physical sports or downhill thrills. I know people who maintain as a personal goal hitting the slopes 50 times a season. Different strokes.
Audiophiles need to loosen their grip on the absolute sound for a few minutes now and then and smell a few flowers. We have 5 senses at our disposal. Let's use them all and not worry about which sense others favor.
