Nobody wants to pay $1600+ for a graphics card. However, Nvidia is not taking advantage of customers, but is the scape goat for global demand increases, supply shortages, and further government regulation. Its margins are not as deep as you think; in Nvidia's latest earnings report, its profit margin was around 20%. So every $1,600 card that you buy, Nvidia earns $320. Even if NVidia sold the cards sans profit ($1,280), people would still say they are too expensive. The cards themselves are more expensive to make and the technology requires more expensive talent. A better target to blame is TSMC with its 50% profit margin. Thankfully, the United States and other countries are investing in chip making alternatives to increase competition and reverse market hegemony. Everyone would like to revisit the halcyon days of paying $300 for the best graphics card, but then we'd be playing Hogwart's Legacy at 10 fps. Tom's Best Graphics Card list shows you can still purchase a great graphics card at $300, just not the best out there, and unfortunately, most seem to only want the best.
Edit: While 3dfx Voodoo was $299 back in 1995, it was a graphics accelerator not a graphics card. It required a separate graphics card to operate and was not standalone. Nvidia might not be the inventor but they have significantly contributed to creating standalone graphics cards to power consumer gaming needs. For full disclaimer, I am an Nvidia shareholder.
