I agree with you. This is why populations, no matter which population it is, are more likely to accept the government who has substantially increased the quality of life of the average citizen. This is a very hard position to disagree with, I think. Many citizens in the Western world also have had stable political systems despite the massive wrongdoings of their governments because for the most part, governments have not overstepped their bounds in comparison to the stability provided.
It's like having a goodness-to-shittiness ratio that each citizen subconsciously evaluates with an accompanying flowchart. The average citizen thinks to himself or herself: Is my government doing bad things? Yes. Is my government doing good things? Yes. Is the government doing enough bad things to make me care? No. If the answer is yes, then the next question is: Do I care enough to do something about it? Most of the time, the answer is no because society pushes me to remain being a busybody (job, life responsibilities, etc.) or I just don't care.
> Could you point to a specific year in the 20th century after WW II that no Western government was conducting an unethical experiment?
I could have phrased that better: All governments are capable and have a history of some kind of unethical experiment. I think that it is rarer that it is at this level of scale and with this level of technical sophistication. My thought was that generally, a Western government would not successfully pull off this prototype with neither the degree of success or extent.
I personally do not know what is happening at the granular level and I do not pretend to know. I wish I did, and for that matter, at any point in time there will be shady things going on that we do not know. Maybe we will learn in a few decades.
For the first time, we get to see what control through the digital lens of information technology looks like when combined with the capacity to enact state-sanctioned violence. It's like the cyberpunk genre, except privately-owned corporations do not yet have a significant capacity to use violence. Maybe we'll have the honor of seeing that by the end of this century.
On that note, the closest thing the USA has done in subjugating populations of citizens in a systematic way is the internment camps of Japanese Americans for no reason. They apologized 4 decades later. What good is an apology if you've been waiting for most of the victims to die anyway? Nonetheless, it still gained notoriety (eventually), and people still fought for recognition afterward.
