Simply put, the world works like this: We all have needs to sustain our life, and we therefore all must endeavor from cradle to grave in the satisfaction of life's requirements. Wealth, you see, is anything that can be utilized in meeting our needs to sustain our lives.
Wisdom and experience show that some wealth assets are more reliable and universal. Some are so reliable, and so universal we actually give very little thought to counting them amoung our assets. Take oxygen. Most of us as we walk down the street give this nary a thought. We are oxygen rich! If you don't believe me, just think of what you'd say upon hearing of a scuba diver who ran out of air while exploring some underwater cave. "Poor bastard." At least, that's what I'd surely say.
So, unless we anticipate scuba diving, very few of us take any effort to mindfully or aggressively gather for later use the real wealth of oxygen. And to any primative, or to a resurrected ancient who had no concept of scuba diving, we would surely look like the perfect fool bottling air in preparation for the event.
To keep this short, let me come to the point. We have basic material needs of food, clothing, and shelter. Access to energy could be also be included in the list. To have more than you need for satisfying the immediate demands for survival is to be wealthy. To come up short in the ability to satisfy any one vital need quickly reveals you to be another "poor bastard" in the eyes of the impartial gravediggers.
Fotunately, from the earliest times of our ancestors we have discovered that we don't all need to be meticulous wealth planners like the modern scuba diver, Mt. Everest climbers, or astronauts taking a ride to the moon. We can generally blunder our way through day to day and year to year in the comfortable fact of life that, through the open market--through the ability to trade with others--we can generally obtain what we materially need in one facet in exchange for some of our own wealth in another facet. Food for clothing seems like a pretty reasonable medieval exchange, doesn't it?
We all know the inefficiencies of barter, don't we? As civilization and trade evolved from the dawn of man to the 20th century, Gold revealed itself to be the single most reliable, universal agent that could be traded in various quantities for anything anywhere on Earth. Maybe most remarkable in this is that Gold is not itself something that is needed or consumed in satisfaction of our basic material needs for survival. But due to it being perfectly and uniquely suited for this universal role in trade for any other person's available wealth as necessary to meet our own specific needs, Gold has become such a near proxy for the real wealth we require for life that many of us have permitted ourselves the casual inclusion of Gold into our otherwise strict definition of wealth.
Those in the financial industry have come to call this universal wealth asset (Gold) by the name "money," but that unnecessarily confuses the issue. In their efforts to facilitate various objectives in modern life, those in the financial industry endeavored to master the alchemist's craft--to methodically create "money" from such substances as worthless base metals or from paper. Even the village idiot can clearly see that "the bankers and others" didn't succeed in creating Gold. But the village idiots were never so sure that these nickel coins and paper notes weren't in fact successfully turned into this other thing that the experts called "money." As for me, I'm comfortable calling these lesser creations by the name "currency," and further, I recognize that they can and do serve a useful purpose in modern society. With this distinction I am not so easily baffled as the village idiots into thinking that these currencies created in the image of "real money" can actually attain the superior wealth function of the asset they sought to imitate--that being Gold. And you shouldn't be fooled either.
Every currency made in imitation of Gold goes hand in hand with the financial architecture that supports it right into the trashbin of failed efforts, and are logged into the collective wisdom of those who vow not to be fooled again. Based on the "conception, care, and feeding" of the various currencies and their supporting architectures, the lifespan--or timeline--of predictable rise and fall milestones may vary in length from one currency to another. They may serve a purpose while they last, but they all suffer the same eventual demise at the hands of inflation. Remember, these currencies are man's artificial attempt, time and time again, to imitate Gold for use in modern commerce. They are built for speed--built to be borrowed specifically, and spent rapidly! They are not suitable for saving. For that you must turn to the master--the near-wealth proxy upon which all currencies must bow down in inferior imitation.
So you see, learning how the world works is all about each man coming to the understanding about the real wealth we all require to best ensure our survival. Knowing that Gold is the master proxy for our life's day-to-day and year-to-year shifting requirements for food, clothing, shelter, and energy, it simply makes more sense to gather in Gold for later use than to gather in clothes (that we may outgrow,) food (that may spoil,) houses which are more than our needs, or energy (that we can't store.) You see, time bears witness to this undeniable fact: Gold can be called wealth because it is an enduring wealth proxy in exchange for our life's needs. Currency, on the other hand, serves a specific modern economic purpose--to be borrowed and inflated in placation of man's immediate desires. It is not wealth, it fails as a proxy for the Gold it tries to immitate. Do not confuse the two.
Understanding how the world works is easy as soon as you understand the Wealth Hierarchy. Like this: Earn money/currency, buy what you need, save Gold, enjoy what life has to offer.
Real wealth. Get you some.
