As % of GDP? Gee that mightn't be because the GDP and revenues plummeted would it? And aside from automatic raises in spending for social security, what do those graphs say about cuts in other areas? These are very misleading.
There's no actual debate on whether or not austerity measures were implemented. They were, and the governments of said countries brag about it, or are pressured into it. And suffer for it.

Yup, that's some real bone-cutting austerity right there... </sarcasm>
