I'm glad some people agree with me.

I'll even step out and make a couple predictions.... Nostradamus step aside.
Rant on....
What we currently think of the high-end will die a slow death. I'd say within the next 20 years the market will shrink to obscurity. By some standards it already has.
The reasons are simple.
Reason #1: There are too many competing forms of entertainment. How many of us spend more time on the computer than listening to our stereo? How many of us spend more time watching the tube? New audio formats will appear that match video/computer standards for audio. The HT systems will get the hardware in place and once there is an installed user base of hardware the music industry will supply software to that market.
Reason #2: The spread of free information and the free flow of goods from international markets. All young people research things on the net. Almost none of them perceive the high-end audio magazines as credible. For good reason... they have lost all credibility in most cases for supporting claims built on sand. The free flow of information and goods will kill the traditional 2-channel audio store.
Reason #3: I also agree the future generations in North America will likely be less affluent. There will always be the rich that can afford whatever they want but there won't be a large middle class with the amount of disposable income we have had in the past. They will be paying most of their income to health care, education, paying interest on government debt and paying for a social security system that is a time bomb. Also... energy and all commodities promise to raise in price as long as there are developing countries and growing populations. Overall we will learn to survive on less disposable income.
Don't get me wrong... there will still be people cryo treating their wires and elevating them. The internet allows small groups of people with the same passion to gather across long distances. The group will be smaller than it is today though as the institutions proping up false gods are going to die a slow death or they will morph into something else.
Rant off....
