It is a subject close to my heart, with my wife being Greek it is a second home to me now. Anything that reminds people of what is still going on now is a good thing but you can't underestimate how long it will take to get this country back on its feet. Financial bail outs have formally ceased so government will continue to cut pensions and salaries, raising taxes as well. It's grim.
I've a friend who has a Greek parent, and she loves the country dearly. But it's her view that Greece's financial woes are in large part due to tax evasion on a massive scale. She says that many Greek's simply don't bother paying taxes and the system is incompetent (or maybe corrupt) and doesn't crack down on this. So you have a substantial portion of the population as free-loaders being supported (or not as the case may be, as the money has run out!) by the rest.
I would say the problems are more due to various systematically corrupt and incompetent governments going back a number of decades. I have had many enlightening conversations on the subject here. Yes there is an issue about tax evasion but it is not a simplistic one - when you are aware of persistent corruption at the highest levels and misuse of public funds, you can imagine that the incentive to pay taxes for undelivered and underdeveloped public services is greatly diminished. Of course the government needs to collect these taxes but there are any number of new taxes that are crippling people who do pay up.
Furthermore you now have a totally inexperienced left-wing government with communist leanings that promised an end to austerity but when reality came to bite they caved in and put up all taxes and continually cut pensions with absolutely no clue about a long term solution to Greece's woes.
