Why doesn't Greece default on hits debt if things are really so bad as the article makes it out to be?
That's the big reason why the IMF was willing to bail them out.
The penalties of defaulting are probably already negotiated to far outweigh the penalty of stark austerity measures.
Moreover, the SPV and the bailout plans in the eu seem to be more like smoke and mirrors than concrete stuff (e.g. bailing out greece with money coming from portugal which is in the same position)
Greece debt may be denominated in Euros, but that is the only thing it would have in common with German debt.
