Apple has never been about making all their products “affordable” to everyone. Are you old enough to remember what the original Mac cost in 1984? It was $2,495. That’s over $6,000 in today’s dollars.
More or less agree, but comparing today's prices of tech products to those of 35 years ago is way off base. 35 years of Moore's Law - with the doubling of components per 2.5 cm diameter chip every two years commensurate with lowering costs - has made direct comparisons in pricing over several decades irrelevant. The Cray X-MP/48, the fastest computer in the world in 1984, ran at a base of $15 million sans disk storage. For an extra million you could buy eight 1.2 GB hard drives to go with it. It was, at the time, the fastest supercomputer available. It had a 105 MHz cpu clock speed of 200 Mflops per its two cpu's, and 16 MB of RAM spread across 16 banks. Let's compare that to the current base model iMac Pro: it has 8 cores of 3.2 / 4.2 GHz processor power (effectively 8 cpu's); 32 GB of RAM, not to mention its graphics processor; 1 TB SSD; its price tag is $5000.
So, the base iMac Pro has 30 / 40 times the Cray's processor speed. The iMac Pro has roughly 100 times the storage running at the latest SSD speeds. It has 2000 times more RAM than the Cray. The Cray was 3000 times as expensive as the base iMac Pro, and that becomes even more of a difference if you adjust for 35 years of inflation, and include the highly paid personnel needed to run and maintain it. Using your inflation estimate, that meant the old Cray would have run over $30 million in today's dollars. I agree with your premise, though - you get orders of magnitude more bang per buck for today's product offerings up and down the tech spec line. I still have to question the $1000 monitor stand - it's made of aluminum, not titanium. That thing is a price gouge, but with its experience getting customers to buy $1500 iPhones, Apple might as well see if it will float.
My main gripe about the Mac Pro pricing is with its base configuration. At the base level, the iMac Pro has considerably better specs, the most glaring being 4 times the base storage. The main advantage with the Mac Pro, at base level, is with its ease of upgradability and in not being an all-in-one. If you don't want the $5000 monitor with $1000 stand, you can buy another cheaper monitor configuration.
