Did you read Manolara's post before posting ?
He is clearly stating that Greece is and has been a dysfunctional nation economically. They should never have received the loans they got.
As to why the loans were given, we can only speculate.
1) The EU, IMF, ECB did not know this. In this case they are manifestly incompetent.
2) The EU, IMF, ECB knew this but were optimists. In this case they are manifestly unwise.
3) The EU, IMF, ECB knew this but gave the money knowing there was a good chance Greece would get into trouble. This then begs the question, why did they do it ? And that question has many possibilities.
When you are a small player you have to play by the rules. But when you're a big player you can always move the goal posts.
My understanding of Manolara's post is that ALL of the blame going onto Greece and its citizens is grossly unfair, as they are not 100% to blame. Now if we want to work out what percentage of the blame should be on the current Greek government, what percentage on previous Greek governments, what percentage on its citizens, what percentage on the EU, what percentage on the IMF, what percentage on the ECB ... that is another study in itself.
As to "good" citizens in Australia paying their taxes, I can assure you they wouldn't be such good citizens if they could easily get away with not paying tax. They pay because they must. Because it's not easy in Australia for the average person to get away with not paying. Because if the ATO catch you out, they are relentless in collecting the due amount and are also very well staffed.
P.S. I really hope the upcoming vote for Brexit leads to the UK leaving the EU. It's time the EU copped a good kick in the teeth.
