Big deficits, which result in huge debt, are a tool by which wealth is taken from future earners for redistribution to special interests today. Essentially, it's a method by which unprincipled pols peddle influence and buy votes. Given the current political system in the US, government has no motive to solve the problem. Both parties pump out rhetoric about controlling deficits, with the demwits tending to talk up higher taxes and the retardicans lower spending, but once in power neither party reverses the direction in which the national state is going.
It may be valuable to recognize that the national debt is owed by the nation-state of the United States, not by the nation of the American people. That may seem a distinction without a difference, but as the runaway train of the US government hurtles down the track toward its inevitable wreck it may become a more important one. Whether or not it does has no effect on the direct answer to this question, though. The US will not get out of debt. It cannot. The die is cast.
