I just checked the BM and the Spyderco website for MSRPs:
The BM Griptillian, a perfectly fine knife with for everyday use is priced at $160 with S30V steel
The Spyderco Endura, imo the equivalent in VG10 costs $136.50
These knives are/were the "standard high quality" knives with a decent steel and will work amazingly well without any issues. Non knife people buy one of these and are happy for many years.
With the proliferation of better & way more steels, more exotic scale materials and the overall cost that went into this richness of variety, you will have knives that are more expensive.
Companies that are not trying to ride this surge in demand of high quality & variety knives, will just stagnate.
The cost to accomodate the variety in process and production is initially high, but with the prices so high, you as a company can calculate the ROI and see that you're not out of your depth.
This is also true for other industries, but with every "hobby" there's just no limit of what people are willing to pay.
Personally, I won't buy a BM, as I don't like the axis lock. (too many parts, weak omega spring)
