I'll leave aside the ad hominems, and address the core of your arguments.
From what I've read there appears to be consensus across the board that the Greeks approach to taxation is currently too complex, and reform of this tax system would be sensible.
With that said, there's a fundamental misunderstanding of what's happening with these loans. Read this...

"When the IMF, European and ECB bailouts began in 2010, €310 billion had been lent to the Greek government by reckless banks and the wider European financial sector. Since then, the ‘Troika’ of the IMF, EU and European Central Bank have lent €252 billion to the Greek government.[1] Of this, €34.5 billion of the bailout money was used to pay for various ‘sweeteners’ to get the private sector to accept the 2012 debt restructuring. €48.2 billion was used to bailout Greek banks following the restructuring, which did not discriminate between Greek and foreign private lenders. €149.2 billion has been spent on paying the original debts and interest from reckless lenders. This means less than 10% of the money has reached the people of Greece."
Furthermore, there's a common misconception that the Greeks are lazy, but the statistics show that they have the longest average working hours in Europe, and their average retirement age is not that different from the rest of Europe.
As for Argentina, yes they're not out of the woods yet, but since their economic crash they've had impressive growth. IIRC it's been the fastest growing economy in South America recently, I'm sure I could find the stats if you disputed this.
So, with all this in mind, why do you think more loans is the answer?
