The older generation has a lot of bad habits (which in a warped romanticized way made Greece special and at the same time somewhat brutish and refreshingly untamed to me) which contributed directly to the economic mess. Over the last few years (I visit every year) I have seen small steps forward in mentality of a few people young and old, but they are not the rule rather they are the exception. Nevertheless progress is progress even if it is slow, and some don't wish to change, long term these bad habits will be history, how long exactly is anyone's guess.
