Mass surveillance is nothing new. The USSR had an absurdly wide surveillance net paired with endless on-the-ground informants making people terrified to speak pretty much anywhere, yet as soon as things started slowing down the entire system collapsed with a shocking rapidity, because these things don't create social harmony, they create a dystopic nightmare that people want to overthrow.
However, people are willing to tolerate dystopia when real wages are skyrocketing, your nation is doing wild things (like radically advancing human spaceflight), and more. But as soon as all of this slows down you're left with the same uninspiring directionless stagnation that plagues all nations eventually, and a dystopic social system on top.
