As the spectre of default and more financial straits loom for Greece, Germany has undertaken some demanding roles (EN/DE), though commensurate with their overall economic influence, to rescue Greece and the European common currency. 
Involving private investment is necessary and smart move on the part of Germany--however, the tables could still turn on everyone. Another avenue to pursue, I think, might lie in rallying and educating the general public. A lot of solidarity emerged for Egypt and the Arab Spring, and although the Greeks are not suffering like their compatriots in the Middle East and North Africa, there is potential for injustice and for the crisis to spread. Surely there could be an educational campaign on the part of EU governments to show consumers what choices they can make to help Greece--or Ireland or Portugal or Spain or Italy. I don't know if one can buy a Greek-made automobile as easily as going to a Greek restaurant, but there's surely something useful that could be done and presented as an option--even berthing ones money in a Greek credit harbor overnight might make a difference. Whether skeptical of the euro and the EU or not, everyone too has a vested interest in helping keep one's neighbours and partners afloat and thriving.
