As government debt is equivalent to private sector savings (ignoring foreign savings for simplicity), it is fairly easy to see why governments run near permanent deficits.
As the economy grows, the private sector tends to want to save more. Hence, only the government is left to take on the debt (unless you want to involve the foreign sector and run a massive foreign trade surplus, but that is just moving the problem up to the international level instead as it is basically a zero sum problem)
That said, there is no reason to pay interest on all that debt. To allow more private sector savings, the government can issue currency with or without interest. However, the same people who whine about the debt tend to also complain about "monetizing the debt" (a.k.a. issuing zero interest debt).
