The word healty can be loosely used in relation to money. The word healty has various other meanings, mostly in the context of finance. Generally in the United States the word healty tends to be used when referring to how money is purchased and sold, or simply how goods are purchased and sold. However in some countries the word healty means a more abstract way of talking about money, perhaps something like “a loan on commodities.”
Most modern economists consider healty as a synonym for money. Money, of course, is a product of human activity, just like food and oil are products of human activity. Just as money is a necessary part of society, so too is healty. And just as money is a productive good, the sale and purchase of goods, and in particular the exchange of money for goods, is a key element in the operation of the economy. Without money people would not be able to buy or sell, they would not be able to access bank loans, and they would not be able to use their money to acquire the many goods and services that are essential to the operation of the economy.
But money itself is not healty. Even if it were, then money would not be exchanged between producers and consumers, as it is the exchange of goods for each other. Money is merely a symbol for the various productive goods that are produced. If you produce useful goods and you want to sell them, then you will need money to do that. That is how you get your money, through exchange. So it would be incorrect to talk of money being healty.
The price of a commodity is determined by supply and demand, just like the price of any other good. In traditional market economies, prices are set by the supply and demand forces operating on the market. It is not healty, per se, that determines the price of any good, but it is the way in which money enters and leaves the market, and the role that banks play in determining the level of bank interest rates that determine the relative amount of money in the market.
So it would be misleading to talk of money being healty. The money of course enters the market when you make a purchase of goods. But the money goes out again when you sell the same goods. Money is both a means of entering and leaving the market, just as food is both a means of nourishment and a means of livelihood. And just like food, prices tend to vary according to the supply and demand conditions prevailing in the market. And this has been the basic law of healty ever since Adam and Eve ate of the apple.
Money is obviously necessary to buy and sell goods. And no doubt, without money, people would not be able to purchase anything. But money, like food, has to be kept in balance, just as you would want your meal to be balanced. If there is too much of it in the market, prices go up, and if there is too little, prices go down.
