I think it helps no one to say "debt is high" or "debt isn't high" - relative to what? In absolute terms it's huge and a first, in relative terms you may always find a measure that says it has been higher before.

You're a proponent of Keynesian economics then. How do you counter the argument that no government spending is ever only temporary? There's no such thing as a temporary countermeasure in politics. So spending now in all likelihood means spending forever. And that is surely not good at all. No politician ever will seriously reduce spending when all is well. Keynes is only cited when times are bad..
