That's what you get in a world where damn near everything is measured against some objective criteria, analyzed by a 3rd party or tracked by the government or someone at the behest thereof
None of these things measure "not an asshole". They measure results. The incentives from there are obvious.
The business owners who treats employees, customers, vendor, everyone like shit in his quest to produce the most widgets, juice every stat, is the one who gets the attention from investors and the one left alone by the government.
Someone has never heard of a medieval peasant. Or take your pick of ancient slave...
Maybe your theory is that if you weren't alive in the past to see "an asshole" for yourself, then the prudent conclusion is a sort skepticism about their very existence.
I wonder how you envision the past then... a vacant landscape? Perhaps you actually believe human nature has radically changed just in the past few decades? The odd thing is I think an actual analysis might contradict your claim, that is if the measurement is simply who is "an asshole". Perhaps we would find more surveillance actually reduces "asshole" behavior generally. Like how confrontational people often change their behavior when confronted by a camera, .etc
