"there needs to be a fundamental shift in thinking so that quality of life is measured in entirely different ways."

That is going to be long and slow.  I spend a lot of time on home theater forums (a very fun hobby which I will miss tremendously).  There are a bunch of very smart, very knowledgeable people on these forums.  However, almost uniformely, they spend an amazing amount of time talking about advancements in the future, how much prices will go down, what the equipment will be like in 5 or 10 years.  It is almost sad to think about what a shock the future is likely to be to these guys.

They could move closer to each other and cooperate with building a little larger theathers where they share the electronics cost and input a lot of their own building work to get good acustics.

They could then recover some of the cost by selling tickets...

It wont be home theater any more, but small scale theater.
And it would generate social capital for them.
