Why does money have value? That is such a good question, one that I have never really bothered to think about or answer. I believe that money only has value because people give it money. They know that money is just paper, unless value is assigned to it. People understand that more money means they can buy more products. Thats why people work so hard. They put in their services to makes more money. More money means they can exchange it for things that they want. Its as simple as that.
How much value does money have when you are freezing cold, with 1 million dollars, and in the tundra by yourself? Absolutely zero. None at all. Why? Because value only has money when people give it value. The only value that money in that situation would has is to burn it to stay warm. Thats it. Same goes for having american money in another country. It has no value unless you exchange it because the people there see no value in it. They can't do anything with it. So what is the value of value? The value of money is exactly what YOU give it.
