Privacy inequality exists, and it goes the other way, at least in the west. In practice, the richer and more famous you are, the less privacy you have.
If you are rich, you are a target for everyone who wants a part of your money, from criminals to opportunists. Stars have their paparazzis. And even in their inside world, the rich typically have many people working for them. If you don't drive by yourself, your chauffeur knows where you are going, your accountant knows how you spend your money, your cook knows when and what you are eating, etc...
It has serious consequences. It very famously killed Diana for instance.
And think about "the fappening", where celebrity nudes leaked out. It is not the king of things that happen to average girls. I know someone who "revenge porned" his ex girlfriend, it didn't go far. She is pretty but average, and no one took interest. That's what protected her privacy.
The author mentioned things like targeted ads, where only the rich can opt out. Sure, but if you aren't rich, where is the big deal. Advertisers aren't after the money you don't have. Maybe some company have a lot of details about your life, but no one will really care. OTOH, the rich and famous have actual people tracking them constantly. The fortunes they spend for their privacy and security only gets them what we naturally have just by being average.
It is interesting to note that in 1984, the ones who enjoy the most privacy are the proles, the lower class.
