Take Germany for example. Germany is not growing its debt for 5 years now. And they are decreasing their debt passively by issuing bonds, those bonds have negative ROI at the moment, so each year, Germany is decreasing its debt by using stupid banks, assurances and big money investors who think that their money is safe in the hands of the German state (total BS by the way, if the euro collapses which it will, those guys will lose all their money invested in those bonds.

That has some good effects, but also some very bad effects.
Yes the debt burden is shrinking which is good, but the liabilities are increasing without people noticing.
Whats negative? Debtors such as greece, italy, spain and portugal are going to default on their debt. - Germany will pay for it.
Banks are going to die - Germany will pay for it.
Italy will leave the EU next, Germany will pay for it because it will likely kill the EU.
The last one on the sinking ship will pay for this mess - this will be Germany.
So the reduced debt will end in the same way as if they would increase their debt by 2000%. They are screwed...
