Riley on the Trashfuture podcast made a very salient point on government spending and debt the other day. In short:
You loan money to entities you believe can repay it.
Governments loan to themselves (possibly with some extra steps, but basically).
Governments going into debt is thus a measure of the governments beliefs about the future. More specifically, loaning money _now_ means it thinks it'll have more money in the future.
That things will be better.
