As I explained in another thread, the total national debt is growing at a rate of about 7-8% per year, while the GDP is only growing at about 3-4% per year. In other words, our debt is growing twice as fast as our ability to pay it off.
This is why Clinton made paying down the debt one of his top economic priorities for eight years (while the flying monkey right was more concerned about who he was diddling.) When the Boy King was appointed, the repukes reversed everything Clinton accomplished. BushCo = the borrow and spend administration.
If there's a crash coming in the next five years (and I think there probably is), it's something that's been building for a quarter century, and there's really nothing that can be done to stop it at this point.
Fasten your seat belts--the crash could make the great depression look like a picnic.
