That's actually part of my justification for ordering an iMac Pro now: my 8-core Mac Pro (2013) ran out of AppleCare earlier this year and at least once per week it's been failing to power on.
There's no way I'm going to spend a large amount money on a repair for it (and you know a Mac Pro repair is going to be expensive), when I could put it towards a newer, more powerful machine.
At the end of the day, it's a tool of trade. Good tools cost.
Anyway, we see the 5 figure price points and think it's a lot, but it's probably not even in the top 5 of expensive Macs in the past. There was the Lisa aka Macintosh XL, the Macintosh IIfx (which on a family forum I can't print what the "f" stood for, but the "x" stood for "expensive"), a PowerMac 9600, etc. In modern day dollars, these would have been over $10k.
Even the original, basic 128K Macintosh was $2,495 in 1984 dollars, which depending on how you measure value over time, comes to around $6000 if just multiplied by the CPI, but really more like $8,410 if you take the income value (the relative average income that would be to use to buy a commodity, using GDP per capita).
