If people want to suffer less (long-term) there is, as I see it, only one reasonable option: emigration. Of course, this option might shut in the medium term. This is especially true if you are young and un(der)-employed: it is pretty clear that groups that still have some form of rent are not going to give it up easily and people that are out of the system (the aforementioned young) are already shut of most benefits of a modern western society. So: run away, while the borders are still open... If you have people you care that stay behind, remit them something from outside.

It is difficult not to see Greece (or Portugal) not to become a failed state in the medium run. People should prepare accordingly (in individual/family terms, I mean).
