My argument was going to center around common places where surveillance happens - engagement tracking at grocery stores, license plate readers on traffic light cameras, and the like. It's hard to opt out of roads or grocery stores. But then I realized that even these reflect the gradient. Maybe big box stores like Walmart are deploying these technologies - are white-collar workers actually shopping there, or are they instead going to smaller, boutique-y shops who don't install them? Are traffic light cameras going into upper-class suburban settings, or are they first being deployed to major roads and arteries?
So... I've more or less proved my initial thought wrong - this gradient does indeed persist, because people at higher rungs of the ladder are self-selecting for experiences which don't feature these kinds of surveillance (even if that is not their primary reason for doing so).
