Money runs the human world. Really, power is in the hands of a very few people already.Those who control the worlds purse strings, have the most power. Even countries depend upon international banking, credit and lending. Right now, the world currency is based upon the US dollar. There are people working constantly to undermine the United States position as a economic power. China is trying to replace it with the Yen, as we speak.
Would they ever hold total world domination? Not in the sense that they will rule every humans entire day, from sun up, to sun down,birth to death, but they can control consumer goods, lending, credit and currency easily. They could manipulate so many things that modern people count on.
No matter what happens,I believe an opposite reaction will always occur. Because,for every action, there is always a related and equal reaction. That is a universal law of nature.
