Trex4:
simple. Because most of the commodities and services the world trades are priced in US dollars. If the USA want's to buy something, it would just print more dollars. Everything, including the phone you used to type, the oil you use in your cars and generators are priced in dollars.

Also note that there's an enormous demand for dollars worldwide and the US isn't even meeting the need.

Telling you how to generate currency sound presumptuous to me.Generating currency is not a hard thing, as long you make yourself valuable, you will always get paid according to your value. Over time in life the knowledge will accumulated increases our standard of living it called productivity growth. My point is time will come, when a person will start generating income according to the knowledge he or she has acquired in life. A doctor get paid for his knowledge, just as a lawyer or a mechanics , the more valuable your knowledge his the more the money you can receive. Someone who sweeps a building receive little money, because anyone can easily do that, there is not much knowledge required in sweeping a building, so their economic value is low and thus their reward will be low. So I will tell you, if you want to generate high income in life, do all you can to always improve your productivity growth. Because in the long run it is all that matters.

thank you for your time

How? Why?

Shedding more light on what trex4 wrote, the USA are able to print more currency than any other countries because their money the US dollar made up the Highest percentage of the money in the world reserve market. The US dollar has 55% in the world reserve market followed by the British pound 35% followed by Japanese yen 15% and the Chinese renbi 5% although Chinese currency is gradually or rapidly becoming valuable in the world markets. The USA has the privileged to print more money than any of the other country listed above, although they too can print money but only little mostly according to their dominance in the reserve market. A country that has it currency dominate the reserve market can do a lot for it citizen than any other country, when in trouble they can easily print more money to bail itself out. This privilege is far greater than having military power, that is why most countries do not want to wage war against a country that have it currency as the highest ranked in the world reserve. But this ability to easily print money comes with a price. Yes, its devalues a country currency slowly until it becomes useless and as to be replaced by another stable, economically prosperous country currency( A new world order). Devaluation as been the sole caused of a new world order since time in memorial. It is the reason worldpower shifted from the Dutch to the British and currently the United state.
