I finally found all possible justifications to the labor, raw materials estimates wires vs. other thingies.
It all merges into the meaning of toy vs. tool or instrument. In the toy department (for children) everything is inflated because of "mama buy me this" market factor (MBMT) is always present so mathematically (what I like most alas from any science behind) it looks as follows:
(Raw materials + Labor) * MBMT.
Note that in wires reaching the price of new car right multiplier always approaches to unity while MBMT approaches to infinity -- no need of knowing any electrical or performance properties as they easily factor out!
The value of MBMT usually contains tons of propaganda and advertisement -- which IS actually LABOR oriented to drain funds of baby boomer's foolish children.
Bypassing all science behind on how good or bad wires sound (do they sound at all?), the most honest value to the product belongs to Mogami and most of pro-audio brands. Mogami Silver series (ones preferred by me) provide better electrical contact than gold according to per-unit resistance/impedance. They run in the range of $25/m pair.
