On Paul Krugman's The third depression

The point is when one starts looking only at the dimension of governmental expenditure and not to the quality of it. Governments should deliver positive expenditure into the economy. That means have the basic current expenditures to ensure an efficient operation of the required services and then investment that generates sustainable growth in the economy. The shift that is nowadays necessary is to turn improductive expenditure into growth generating one - and not spend money just because the simple act of doing it is positive.

And, if you generate growth, than, naturally, your issues on debt weight on your economy will decline, for 2 reasons:
- tax revenue base will increase, meaning an increase on revenue;
- the economy basis against which governmental deficit is measured will increase, meaning the percentual (the meaningful measure) will decline.
