Somebody's savings is somebody else's debt. The whole world can't be a net saver, as nice as that would sound.
The counterpart of debt is credit, not savings. Having savings is necessary to be a creditor, but it doesn't imply being a creditor.
I always liked to imagine that, ideally, an inflating currency would proxy for this real wealth-generation, but that doesn't quite seem to be the case.
Anyway, the important thing is that we're not (simply) printing money. The world gets richer.
