Nothing more true has ever been expressed.
> This implies a value on wellbeing, and if the well-being of other living things didn't get in the way of their own wellbeing (assuming they didn't care this way or that about others) I don't see why they wouldn't say "Others having good lives, why not?"
I'm always amazed at Russian, Iranian, and North Korean politics. I would think Russia would say, "Hey, we have enough land and people. Let's just be happy and wealthy Russians." I would think Iran would say, "You know, live and let live." I would think North Korea would say, "Our people have everything a human could ever want. Let's just build our infrastructure even greater than it is."

But you know, they don't. We don't get in the way of Russia's wellbeing, or Iran, or NK. Some cultures just aren't satisfied with the status quo, but seem intent on disrupting the wellbeing of others.
