Everything can be and is created. Wealth is no different. Take a look at the value of an enormous corporation like Apple. Where did that value come from? It was literally created from nothing more than imagination. Forward thinking people dreamed of products like iPhones and Mac computers, etc., and then they brought them to life by building these amazing objects out of resources, all of which would have no value whatsoever if not for technology that bestowed value upon them. Where did this technology come from? Imagination.
Do you believe that resources have intrinsic value? Did you know that prior to the invention of the internal combustion engine that oil was thought of as nothing but a nuisance? It bubbled up from the ground here and there polluting otherwise pristine land and streams. Nobody wanted land with oil on it, and no one imagined that there was a whole bunch more of it under the ground or that anyone would ever want to access it even if there was. But technology transformed this useless dirty slimy goo into what many people now believe to be one of the most valuable resources on earth.
And then technology created better and better ways to extract it from the ground, to refine it, and to use it. Many people are stunned to learn that today, despite all the hand wringing over depleting oil reserves, the known resources of oil in terms of years of burnable fuel are currently greater than they have ever been in the history of the world. We literally have more years worth of available oil resources than we have ever had, despite the fact that we are simultaneously burning far more oil in far more places that we ever have in the history of mankind. And on top of that,despite what you've probably heard, it doesn't matter if we ever run out. This is because, if that were to happen, technologies would emerge to solve the problem by replacing it with other resources that are also likely currently worth nothing.
If you follow this pathway back to the origins of mankind you would discover that our first energy resource was wood, and there was a time when the English were in a panic because somebody figured out that it was going to be impossible for the supply of wood to keep up with the ever increasing demand. Not only wouldn't people be able to heat their homes, but they wouldn't even have anything to build those homes out of, nor would they be able to build the furniture that was needed inside of the homes. But did we ever actually run out of wood? Not even close... and we never will. This despite the fact that some people want you to believe that we need to conserve paper in order to save forests - the notion is patently ridiculous.
If you are willing to take a close look at the way economics really works you will probably discover that a lot of the things you have been led to believe for your entire life simply are not true.
