So what's changed? Inflation.
199 would be a. great price but INFLATION. Your 199 would have been more like 167 ten years ago. Were consoles 167 ten years ago?
What people get paid has no correlation to what things cost.
At then end it means people have less money to invest in non primary needs. People can live without a console and gaming. And it showed, the PS4 sales fall from a cliff because people who don't want to pay 299 euros for a console will not buy it. This is the worst Playstation sales of all time in France for 2020.
The people who buy a PS5 now and in the first 4 or 5 years aren't the same people who will buy a PS4 7 years after release.
The money made by Sony comes from games, MTX and service sales. They can lost some money on consoles but with process node begining to be pretty expensive it seems go 7nm with PS4 Super slim is not interesting and with a lower price 249 or 199 euros. The goal is not cost reduction only but for the PS4 to be a cheap point fo entry for late adopter but it seems this segment of market will not be reachable by Sony.
