A big part of that ideology hinges on it, so yes it does. That doesn't mean that austerity is the magic pill to solve everything, but when Greece on their turn showed up to how many meetings unprepared? Unwilling to talk? Forgot that large part of the crisis how the government conducted themselves, mostly because they presented themselves as good populists who were going to solve the entire thing and it wasn't going to happen completely painless, well we you get elected on such a lie, it's easy to say that fiscal conservatism doesn't work because you're going to be looking for the easiest scapegoat in sight.
I also want to point out that around that same time Portugal presented their own plan that did not include austerity and it got approved by the EU, begrudgingly and with a good amount of doubt. So it wasn't a matter of forcing any certain political ideology onto anyone, Greece simply had no plan they could put forward as they new the second they did that all those unreasonable promises they said just months ago when they got elected would be something they had to admit were unrealistic.
You're also free to explain to me how you would have solved the structural Greece problem of having many public servants employed for just about anything without shrinking that work force.
It was never presented as a problem of money, what it was presented as that if Greece continued down that path that the actual cost price of recovery would be too great and then it would become a matter of money or more specifically economic reasons. Same thing that is happening now in Italy but we now have all sort of proper alarms in place and so we reacted before it is getting there, in addition to banks being forced to have bigger reserves now which is also one of the alarms that went of to highlight issues in the Italian economic woes.
As for the EU economy as a whole and pinpointing that on fiscal conservatism, to me it just seems you have a boner for that ideology because any fool who followed just a little bit about the EU and it's economy knows it has to deal with a two speed economy and it's the reason why the Euro all in all was a bad idea for the whole region at once, that's where the entire root issue stems from and not from any sort of political ideology.
But since you have such a hard on for fiscal conservatism being "evil", do tell me how you would have stimulated reform without demanding they clean up their house first, and with cleaning up i mean reducing their spending long term on problems that went out of control like a public servant roster that was ridiculously large since you're opposed to all things austerity?
