> the GDR was prescient: They had more than half of their population engaged in spying on all the rest.

Wrong. It definitely wasn't 50%. This number seems to grow each time I see it referenced. The Stasi directly or indirectly employed about 2% of the population, which is still huge. But /The Lives of Others/ takes a lot of artistic license. The true levels will never be known, but the largest and most widely quoted figure is 1 in 6.5 or about 15%. That derives from one historian's estimate, which was that at the upper bound, 1 in 6.5 people had in some way made a report to the government that in some way made it to the Stasi. I'm sure 15% of the people in any developed country have called the police at some point in their life.

This is also assuming no duplicates, you really think the Stasi could uniquely identify and disambiguate informants at this scale? And that every Stasi low level officer tasked with recruiting new informants or else actually recruited new informants instead of making them up and keeping the payouts for themselves?

And because I have to say it: authoritarian surveillance is bad, the Stasi was bad, this is not an apology or minimization, but a correction of historical facts.
