Interesting point. Those things that are most needed (water, air, food) have the least monetary value.You have wisdom WIP. I cannot anwser you.
One thing I do find amazing is how pathetic things are valued in the world.
For example, water is a need, it has value, yet a small stone, like a diamond, is 'value' a million dollars, but it has absolutaly no use and is good for nothing, its just a shiny stone that does nothing.
I think a apple has more value than a dimond because you get something out of an apple, but a dimond is useless, I can lok at the stars if I want to see dimonds.
