That is an understandable perspective.
Here is what I think is possibly being overlooked.
1) R&D isn’t free
2) industrial design isn’t free
3) materials & manufacturing are not free
4) all industries push the boundaries to explore new possibilities in performance
5) life isn’t all about a Buy Now button there is much more it has to offer
6) innovation is what makes mankind who we are.
7) do you really want the world to stand still?
8) Marketing isn’t free
9) Sales isn’t free
10) warranty’s aren’t free.
These are 10 good reasons we see things increase in price. What is eventually free is these technologies trickle down to lower priced products.
Unless you've run a P&L, most folks aren't really aware of running a business and prefer to just complain of prices. Even if that wasn't the point, while I am disheartened by the trend in personal audio over the past 4-5 years, no one is holding a gun to my head to buy gear.
