I’d say it’s a product of Learned Helplessness, combined with Psychological Desensitization.
The government has been grossly violating our rights, the first Snowden revelation was earthshaking, but by now he could give credible evidence that the government has been collaborating with the lizard people from rigel 7 to poison our balls and ovaries, and it just wouldn’t be that shocking. We’ve grown to expect the government to be full of shit and corrupt as hell and a pack of liars, and through our learned helplessness, we’ve mostly decided that there’s nothing we can do about it. If you stand up and make a ruckus, you’ll be killed, exiled or imprisoned and tortured. What else are we supposed to do?
