This discussion might have a different tenor if it weren't dominated by home brewers--which naturally it must be. What if we had others who don't brew but who like craft brew? Would the conclusions about high prices be the same?
I ask because there's a phenomenon whereby often people attribute quality to items that cost a lot. We've been taught this through advertising since birth (think Rolex--it tells time, but that's not what you're buying when you purchase one. You're purchasing a status symbol, not a watch).
Is a beer that costs more a better beer? It may not be that for us, but what about the general public?
******************
I once built and sold custom-built golf clubs. Made a major marketing mistake in that I only charged $20 above the cost of the components for each club. I discovered I should have charged $300 a set more than I did, because buyers wanted a story to go along w/ the clubs. Yes, they were terrific clubs as I had them matched in a way commercial clubs are never matched. Swingweight-matched, moment of inertia-matched, frequency-matched.
But nobody wanted to pull a Mongoose club from their bag--they wanted to pull a Titleist, Ping, Taylor-made, whatever. What I needed to do was charge them more (think Rolex), and give them a story to go with it: "Well, your clubs are off-the-rack; mine are individually matched to a specific specification based on what works best for me, frequency-matched and MOI-matched. That's why they cost as much as they do!"
Lesson learned. I think there's something similar in beer, something akin to a Placebo Effect. This beer is expensive, ergo it must be good, ergo, I will enjoy it.
I've had expensive beers that taste like crap and I'll tell you so. But then, I'm more about the taste and less about the Placebo.

Edited to add: I'd love to do an exbeeriment where respondents would rate the taste of a beer, and prior to tasting they'd be told the beer cost either $3 a pint or $8 a pint, and see if there was a difference in perceived taste. I'll bet there would be.
