Budget Deficit of the US

I refer to a news by Bloomberg, Obama’s Shrinking Budget Deficits Silence Foreign Critics (April 14, 2014) where for example reads the following:

The Congressional Budget Office projected today that the 2014 deficit will be the lowest in six years 

More evidence of fiscal health came last week, when the Treasury Department reported a deficit of $36.9 billion, the smallest for that month in 14 years. Revenue increased 16 percent to $215.8 billion from $186 billion in March 2013. Spending totaled $252.7 billion, down 13.6 percent.

and

Michael Darda, chief economist at MKM Partners LLC, estimates the U.S. deficit fell to 2.9 percent of gross domestic product in the first quarter from a peak of more than 10 percent in 2009. 

The deficit will shrink to $492 billion this year from $680 billion in 2013, according to the CBO, which today projected a gap of $469 billion in 2015. After that, the deficit will start rising every year, reaching $1 trillion by 2023. 

The increase will be driven by “dramatically” rising Medicare and Social Security payments needed to care for an aging society, said Jersey of Credit Suisse.

This is interesting because any improvements in the US' economy are positive for the rest of the world. But we can doubt the real effect of these improvements. As stated, deficit is smallest in a long time, but it is still a deficit large enough to run a small country. And mister Darda states a scary direction for the future. Clearly Obama has been able to make some clear changes, but in the end those probably are not enough without more major changes in the spending and taxation. They could do something as crazy as quit their spending on military, tax tobacco, guns and alcohol more.. but we all know their congress is unable to achieve any true compromises and create changes. Therefore my hopes concerning the future of the US' economy are not any brighter.
