Electronic prices are unjustifiable

I'm not sure what I'm expecting from this post but I just need to vent a bit. I've been using my PC for 6 years now and it's getting close to an upgrade. I bought this one in 2020 I basically put all the best stuff in it and 2x3090 + 64GB RAM DDR5. The cost was 5000 EUROs. Which was really pricy at the time but I looked at it as an investment (still affordable for me) and it held up really nice over the years, not really complaining still does actually. I did the same thing now all the good stuff with 2x5090 + 64GB RAM DDR5 and I was shocked that the price was 15000 EUROs. I cannot justify these prices anymore, how is anyone buying high-end PCs at these prices? Is this just a side effect of this AI craze and things will come down if I wait a bit? Or money just does not have any value anymore? I need to spend at least 8000 EUROs to get a decent enough upgrade compared to what I currently have from 6 years ago. It's just not worth it, I really don't know what to do...
