I struggle with the economies of scale thing. Sure ML can bulk buy but they also have secretaries, the overhead of a large premise, more than one person in R&D etc etc.
The reason I say this is that as a one man band, as is the case in the construction of my Apogees, and probably not far off Roger's case, the bits to make a loudspeaker actually don't cost much anyway. OK rare earth magnets used to make an Apogee are expensive, as so many are used, and China has a monopoly and has raised prices a lot in recent years. But apart from that, the truth is material costs are low. Even for a one off speaker. The ML equivalent is mylar and some perforated metal sheet, with some probably bought in bass drivers (am I wrong here wrt the dynamic drivers?). Above that there are the costs for frames, and bass cab enclosures. Also likely to be low relative to the final selling price.
In my case, there was no middle man (dealer) and Roger sells direct. ML don't have that luxury and have to cope with dealer margins. So basically, I think they have to be more expensive for genuinely competing products. Having said that it is a very complex problem for ML to actually work out what their true costs are.
But as you point out in your last post Rich, there is a bit of a paradox going on in ML's case. I think you can argue the MLs of today are better made than those in the 80s, with better choice of materials, but that, to a large extent, is just a facet of progress in manufacturing techniques and materials. The materials used these days simply weren't available at reasonable cost machined to the tolerances they are now.
In the more special case of the Neolith, that cabinet must cost quite a bit more than say, Monolith's did. So there is a definite justification for a higher relative price, I think, on that aspect alone.
Without access to the true production costs ML incurs, I think it is actually really quite hard to argue exactly what ballpark (to within a couple of K $) the current range should be priced at with any degree of certainty of it being 'fair'.
