Today you simply keep pumping money into the system to keep it alive. Fix the issue? Fuck no! That would be to friggin hard and cost to many politicians their jobs. You do what you can to keep it alive for as long as possible and when it finally implodes you blame it on someone else and say that no one could have seen the problems coming.
You do realize that greeting Greece out of trouble this time will only keep them alive for another month or two. Rinse/repeat. At some point the repeat part of that statement will not occur.
