If the world wants to trade, the United States is basically an unavoidable part...
Why is the United States so important? Because they are the leaders of dollar hegemony!
And as the leaders of the US Dollar, it means they must export dollars on a large scale every year to maintain the liquidity of the world economy.
Thus, the United States will always be a deficit country!
This is why when there's fluctuation in the US Dollar, the whole world catches a cold...
In a way, the United States is the world's number one principal party, and the dollars they export largely keep global trade running.
This year is 2016. Last year, they exported a total of 2.5 trillion dollars, then recovered around 2 trillion dollars through goods trade and services trade, with an actual deficit of about 500 billion dollars.
And a large part of these 500 billion dollars will flow back to the United States through channels such as US Bonds.
