This article is pushing the somewhat racist Magical Indian
myth. The idea that Native Americans weren't just humans, but were somehow endowed with mystical powers and secret knowledge.
You got you covid vaccine that is nothing less than miraculous. We had no defense against the Spanish Flu and hundreds of millions of people died. We now have vaccines and anti-virals and we have cut the total chance of you dying by 20 times. Covid vaccines don't grow on trees.
The fact is that we have doubled the life expectancy of humans in the past 150 years. The life expectancy of Black and Indigenous people are actually higher than ever and the infant morality rates are lower than ever.
And global poverty rates have dramatically fallen in the past 150 years... and the number of people starving has been slashed. 150 years ago, globally, there were many times more people dying of starvation in every part of the globe.
I don't think this article makes very much sense.
