ok, i'll answer 1 by 1...
this one is from goldfinger:
"why don't you get that if Greece goes down in debt it will have a domino affect and push other troubled economies over the edge? Its time for everyone, Americans included, to tighten their belts, suffer the losses for a decade or so, and make the necessary government and societal reforms so that this will never happen again"
ok, 2 things; this will happen again untill someone recognices our right to work 1 day per month and live in a good wealth, since we CAN...
and obviously the Greek population is thinking of it self in first place, and so is the rest of the world... and the Greek population won't just reform because their people say so, they will because the world says so... and you think it's just the Greeks but it's in whole of Europe, don't know about America... however, as pointed out before the Greeks are the weak spot, as soon as another country starts raising huge taxes the people there will riot like hell too... so everybody tries to come out of the reform as good as possible, of course that happens when it goes quicker so that's why they riot, over here in The Netherlands the taxes are not that high but once the reserves will end and then here the taxes will get higher and we start rioting here, so in first place everybody tries to survive the crisis and when you can't wait much longer you try to speed up the reforms by rioting, this is my point of view...
