Greece will be able to afford it's inland commitments with revenues coming in from taxes etc without the euro bailout money but they won't have dough to pay the Troika funds..so best is to default on the loans until the Troika can bring down the interest rate and keep the internal affairs solid..Why is Greece paying loans that Germany makes a huge profit from anyway? When Germany after the war was rewarded with cheap credit it was o.k but they wanna penalise Greece and make it poorer and poorer..doesn't make sense..I can stuff this kind of eurozone lol.
They should default. That's the thing with loans, they are either paid or they are not paid. As varoufakis suggests, they should neither default nor pay, rather push the repayments "into the distant future", that is debt monetization, it is the equivalent of turning debt into money, or printing money, which they currently can't, due to the euro.
When they have defaulted, and continue the welfare state with gross incompetence, they just start a new cycle with a new default down the line. It is the same with all welfare states, it is just that government of Greece hit the wall first among the so called advanced economies. Unsound money is not a solution, it just hides the overspending and incompetence for a while.
