It's actually not only austerity. It's reforming their economy that they haven't delivered on, unlike all other euro countries that needed bailing out. 8% of Greece's population still works for the state. I don't blame other EU states to not take Greece seriously anymore, particularly as everyone seems to forget that 50% debt cancellation that happened in 2011.

All in all a lack of fiscal responsibility and incompetent governments that let down their European partners for the last five years..
