Quote from jem:
I trade gold. But I have no idea while anyone ascribes intrinsic worth to it - outside its industrial uses.
Why gold vs. wampum or shells, or old woven nike shoelaces. It all in the mind.
No, its in the rarity. Gold only exists .004 ppm in the world.
It has value because anyone that has looked for gold knows how hard you have to work to get it. If you know how hard someone has to work for something, you can put a value on it.
For instance...if you know how hard it is to swing a pick and mine for gold and how much gold you find at the end of the day, then you know how hard it is for example to cut down trees all day as that is also laborous work. So if you know how much gold you get by mining yourself, you now know how much to pay someone to cut down trees for you all day.
Obviously economics is not as simple as that and supply of labor, or demand for labor can increase or decrease pay for those types of jobs, but you get my point, I hope.
