According to Wikipedia.org: "In the 29th annual List of global billionaires, a record 1,826 billionaires were named with an aggregated net worth of $7.05 trillion…" Whereas according to globalissues.org: "Almost half the world — over three billion people — live on less than $2.50 a day. At least 80% of humanity lives on less than $10 a day." The fact of the matter is, wealth cannot be created out of thin air, while it can in many countries and families be passed rather easily from one generation to another, and/or be taken from other people or organizations through outright State-sponsored theft; wealth does not create itself, it is created by some sort of labor, and most probably financial legerdemain.
Those that have become extremely rich by creating something of value like to fool themselves by contending or believing that we live in a world that consists of "an economic invisible hand" that somehow produces a fair equilibrium in regards to products and pricing, to which they, these particular skillful game players, are able to profit fairly from. While it might be comforting to believe that each person is given a truly equal opportunity to be successful, in actuality a significant amount of people born into this world, have virtually no hope of ever rising from the abject poverty that they are born into.
In one way or another, the rich depend upon the abundant supply of the poor so that they can utilize them and to exploit them, which allows them to become rich in the first place, or to maintain their wealth, if they already have it. There are very few people in this world that are entirely self-sufficient, that is to say, each of us needs food, shelter, clothing, electricity, plumbing, and well, the internet, of which none of these things just appear out of nowhere, as if by magic. Because a lot of what we utilize can simply be purchased, a disconnect is created between the real cost of these goods in sweat labor, in comparison to what they simply cost us in ready money. This means that the creature comforts that we often take for granted, often consist of millions upon millions of poor people behind the scenes, unknowable to us, and/or their resources that have been either exploited or simply just taken.
The reason why the moneyed elite do not have a vested interest in the elimination of poor people and/or people that is dependent upon their largess, is because their wealth would dissipate quickly. The access to cheap labor and also cheap or undervalued resources are absolutely critical in keeping the superrich--super-wealthy. This wealth also allows these privileged people to essentially rule their domain as they best see fit, and to become untouchable, and sometimes even championed.
The wealth of a country such as America, in so many instances, is based upon the outright exploitation and the taking of labor as well as resource wealth from countries around the world, often having regimes that are easily placated or soothed so as to allow this plucking to take place. The rich understand the value of living to the adage that you can shear a sheep many times but you can only slaughter it once. The poor of this world are those sheep, often ill-educated, ill-fed, ill-sheltered, but typically given just enough to live another day, and given too just enough hope to believe that meaningful change might actually come, never suspecting that their end has already been pre-determined from the beginning.
