Funny you should say that
And "cognitively [un]developed" is a weird way to say it; I wouldn't call that a "bland" term at all.
Interesting premise, do you have a source to back it up?
Edit: or is this a creative way to say "younger" that sailed over my head on first read
It is much more likely that our economic system rewards hostile behavior and that money has outsized influence in politics and a criminal justice system which lets rich people get away with crimes. That money correlates more with hostile behavior then lead, Instead of blaming lead, blame capitalism.
Just think about all the people who put lead in the gasoline in the first place, did they go to prison for their crimes, or did they make a bunch of money and retire in luxury.
You're wrong on every count and simply spreading disinformation. Please don't do that.
Im no history expert but I know there were other Empires thru different times and sizes and places, and since now they're not the same, they "Failed"? Did they fail exactly due to the same problem or others? Are we treating those too? What is our method and how strong did we criticize it and see and understand it flaws?
At a time with fake news, AI slop and whatever the Internet has become today, its our job to treat every statement with the highest from of critical thinking at our disposal.
