>>1Because Greece's economy isn't recovering, their government shows no sign of improvement and is unwilling to do unpopular things to fix it. They are a country with their head in the sand, and by giving them more time it only serves to put them into more debt because they sure as shit wouldn't spend the next 10 years fixing their broken economy.
Frankly, they need to get the fuck out of the Eurozone until they're mature enough to come back in.
