I just think its the "I need the new thing" trend thats been around for a while. Gaming wise someones money would be put to better use on buying a prebuild.
It's been around 2 years since I've done any upgrades to my PC and I still can play current titles at max settings. I actually plan on starting to upgrade it again in prep of getting a rtx 50 series when they come out.
But on the same note I sunk a lot of money into my PC build ( around 3k for just the pc, and around another 1500 or so on "accessories"). This of course was just as the GPU market was dipping back downwards so I paid more than I really should have.
But with 1k ( Lets say 1200 with taxes) you can get a decent prebuild. I mean just searching on amazon I saw this one for 1300
