Google it. There's a wikipedia article on Greek austerity measures.

The third austerity package in May 2010 included selling off 4000 state owned companies, raising the VAT to 23%, and massive layoffs of government workers.

The article mentions pension haircuts and raising the retirement age to 67. The Greek VAT is now 24%. 

The reality is that none of this is going to help. You can't pay ever increasing debt with ever declining revenue. 

They worried about a catastrophe if they went the Grexit route. But they got one anyway. How much worse can it possibly get? And practically, at some point the Germans have to admit they are never getting their money back. Greece just need to pull out of the Euro, default, and start rebuilding.
