You persist in pretending that austerity is a switch one flips or doesn't, depending on one's favored economic theory. That is simply untrue. I am all for Greece spending more than they take in to get out of recession. The problem is that, unlike Ireland (and Spain, and Portugal), Greece has not made the systemic reforms necessary to convince lenders to loan them more money. Austerity is more than simply spending less, it's changing the socioeconomic system to be sustainable.
The European nations want Greece to be a successful nation. Everyone here at AT wants Greece to be a successful nation. But unless Greece comes up with something better than "you forgive the money we promised to pay back and give us tens of billions more until a miracle happens", loaning more money to Greece is simply throwing good money after bad. Europe cannot save Greece unless Greece helps save itself, and so far that has not happened to a sufficient extent. And that's not my analysis, it's the analysis of the IMF and the EU and the EC, as well as private investors. You can froth and foam as much as you please about austerity, but the fact is that Greece has not changed enough to make the largely socialist European states comfortable with sending more of their citizens' wealth to Greece.
