The Stasi existed for 40 years. It compiles between 900 million and a billion pages of information. (some were destroyed)
The archive still exists and is open for searches, so this is not a guess.
Back of the envelope, at a minimum, the NSA/CIA compile that amount every two days on Americans.
The Stasi were complete pikers compared to America’s police state.
This is the most pervasive and intrusive government in all of human history. Not even close. Stalin, Hitler and Kim never dreamed of having this much of a window into people’s lives. It’s beyond what Orwell could even imagine.
They didn't build that Mega-Memory Death Star installation out in Utah for nothing. There is not one bit/byte of electronic information in this country (or planet for that matter) that isn't collected by NSA. EVERYTHING is captured, preliminarily sifted, and stored for later reinspection/use/prosecution.
