Again, “People I disagree with have no agency” is a really unfortunate cognitive failure mode.
Agency occurs in individuals who operate within systems and Americans are some of the most propagandized people on the face of the Earth, and some of the worst educated in the global north. Average reading level is 6th grade. Critical thinking is in the shitter. "I did my own research" is specifically a cultural meme describing how piss poor Americans and many other overseas in the same global north are at both obtaining rigorous sourced information and using it to make decisions. COVID was a demonstration of all of these issues brought to a scale where it became impossible to ignore.
I blame systems more than people because systems should know better, and they largely did, but their ability to act has been hamstrung by one of our political parties holding the line on the notion that "Freedom" means ignorant dipshits with ignorant dipshit opinions should get to weigh in with equal credibility to people who actually understand things, which is a large part of why our government can no longer function apart from passing more fucking tax breaks for people who don't need them while our infrastructure rots and the wife of the owner of WWE dismantles the department of education.
The main reason I don't buy "agency" here is because ultimately the agency of covidiots shouldn't have been a factor either way. We have law enforcement supposedly, I'm told, to ensure the safety of the public. So do it then. Nations the world over that would be characterized as "free" managed to restrict the flow of people and goods in such a way to ensure safety much, much better than we did. Saying "well the people wanted lockdown to end" is fucking pathetic excuse-making on the part of the powerful. Of course people wanted lockdowns to end, they fucking sucked. I too missed restaurants. I too missed shopping. I too missed haircuts. But if it wasn't time yet it wasn't time, and when it was time should've been determined by people in the health sciences who study pandemics, not dipshits from flyover states.
I'm genuinely sorry that a huge chunk of our populace that lives in places with poor economic opportunities and low social mobility get their fee fees hurt when people who study shit for a living say "you're wrong about this" but that's simply a lower-tier issue than the broad strokes health of the country. If the mere notion that someone else who you may not respect knows more than you and is therefore being asked before you sends you into a mental health spiral, may I suggest therapy?
GP didn't say that, though.
Agency isn't some magical axiomatic property where if you exercise it you're the sole contributing factor to your actions. Exercising agency, like making any other choice, is a decision whose inputs include your circumstances, history, etc.
Consider someone who quit smoking cigarettes in the 1950s. That was a time when cigarette smoking was common and not widely considered unhealthy. That person exercised agency. Now consider someone who quit in the 2020s, when cigarette smoking is widely warned against. That person exercised agency, too. More people quit smoking in the 2020s than the 1950s, by any measure. Does that mean people had less agency in the 1950s? No, it means the inputs to their decision-making on how to exercise their agency were different.
