I agree with everything you said except the last part about people becoming mentally weak. Where is the evidence that people have ever been anything different?

I wish I had the actual quote for you but I remember the sovereign individual quoting a report that said a large percentage of Americans in the past were literally considered incompetent. Many couldn’t read. This would explain why old studies showed Americans obeying authority simply because they were wearing white lab coats. They still obey authority today. The majority of humans have and will likely remain retarded. But we keep looking at people in the past as being different/better which isn’t necessarily true.
