The USSR was in a far worse position than the US is in. They had to build a wall to keep people from walking out. The US on the other hand is financially irresponsible. It can't afford a global Not-An-Empire any more because its economy is no longer the world's unchallenged largest but it isn't in a bad state in absolute terms. The scale of the challenges just aren't in the same league.
Unless it decides to go down fighting and gets something important blown up it could easily remain a nice place to live for centuries. Nobody threatens the US, it is hard to see how it'll ever be in anyone's interest to threaten them, they can re-learn how to be an industrial powerhouse if they have to. Almost all its real problems are ill-advised domestic policies that can be changed pretty quickly if people decide the situation is hairy enough to be honest in politics.
It might be in everyone's interests for the US to dissolve but it won't be as bad as the USSR dissolution was. It'd probably be a good outcome if they went back to the constitution as intended, depowered the federal government and became a collection of powerful states. A lot of the political tension is because whoever wins the fight over controlling the central government ends up with far too much power.
