The European people and the European currency would be better without them.
Now everything is gone (almost for the moment) so don't exist more such risks for the euro but the if Greece or some other country of Eurozone will go out of European countries which use euro as their currency, euro will suffer to much. It were be in discussion even its existence. Were and yet are to many the articles in internet that explain in details this event. In this point of view I think that if Greece would be already out of Eurozone the value of euro will be decreased, notably with the main currencies (such us dollar, British pound, Swiss franc and Japanese yen). As for being better without Greece I have my doubt. Even I am very critic with them about to many things and with their behavior in these times.
