The thing though is that these companies are in it to make money so you can't really blame them for raising prices when they are the only game in town and there's such a high demand for their products that people are STILL willing to pay exorbitant fees. That's just supply and demand.
I suspect NVIDIA and scalpers are partially to blame for this. Scalpers hoping to make some quick money on Christmas sales probably scooped up the 4090. NVIDIA probably did not produce enough 4090 chips to meet demand. They misjudged the number of people that are willing to pay a premium. They likely created far more 4080s because they figured that is where the market would be. People claim they made the 4080 in order to upsell the 4090, but I don't think so.
One of the issues driving inflation right now is that it is insanely easy to get a decent paying job if you have any experience in a given field. Even in my particular field, salaries have risen by at least 80% (including my own), while remote work has reduced the cost (particularly in the US) of commuting.
The issue is that these things aren't going to hold. Inflation increases are causing layoffs, and while we haven't yet reached a tipping point (there are still more jobs available than workers), we will eventually. After that, employers will have more power, salaries will stagnate or even drop, and remote work options will shrink. (I am dumping all my money into savings for that reason

)
After that, sales of top end cards won't be so rosy, and we may even see cheaper pricing as a result.
