All for profit companies and even many so called "non-profit" companies go into it with the primary goal of making money.
Obviously, in order to make money you need to convince people that they want to buy your product or services.
I think the part that you are getting caught up on is that not all companies target all consumers, in fact no company targets all consumers.
Mercedes targets a different consumer demographic than Ferrari or Ford, although there may be some overlap between their target demographics.
Just because I don't see any value in current generation NV or AMD offerings doesn't mean that others don't.
Plenty of people still find value in NV products and thus they continue to buy their products. Some might complain about the cost, some might not. But they are still buying the product. NV aren't going to suddenly decide that they don't like making money and start lowering the prices of their products as long as people still buy them.
Now we can all argue that NV are pricing their products out of the average PC gamer's budget which may end up killing the PC gaming market, but that's beside the point because there are still many people with a lot of disposable income willing to buy their products.
So, until people stop buying their products, NV can only assume that they are pricing their products correctly in order to make a profit.
