Those are some profound questions that I don’t have answers for..
I think humans like the comfort of that which they can control, humans like to imagine the worst won’t happen to them, humans don’t want to give up anything so that others will enjoy at the cost of them presently enjoying—
That’s a lot of generalizing which is wrong to do but describes many I see.

Power in the hands of those who get to acquire whatever they want simply makes them feel indestructible—as far as I can see, I have no understanding of this psyche nor will I ever want to understand the greed of money and power over the greater good of humans and this planet.
