For what it’s worth I disagree with this interpretation, though it’s probably cultural. Amazon’s profits have trebled this year and they’ll likely hit $10 billion a quarter next year. They arguably don’t need to increase prices at all, for anyone.
But in any case, attention is a resource, adverts are specifically engineered to exploit it, and charging people to protect their mental headspace creates a two-tier society where the affluent can choose to silence the noise and the less affluent are treated as a resource to be exploited.
If ever you need an example of how capitalism ruins things, you can just refer to the mess that is now streaming services in 2023, compared to where we were 15 years ago. We’ve gone from one or two high quality, reasonably priced services that many could access to a fractured system with escalating costs, low quality content and ads.
