No, I don’t think the casualties in Greece have anything to do with what may or may not happen in other countries. (I am currently in Greece btw)
The Greek financial crisis follows similar ones all over the world, starting with the US itself. It was predicted, and it just took a little longer to happen because typically Greeks make their money from tourism, ie they are always affected by other countries’ situation the following summer.
In terms of numbers, Greece fares no worse than other countries within the EU, and the current crisis is certainly not as bad as those faced by Argentina and Turkey a few years back.
What is very different is the way Greeks themselves deal with such problems.
1. You are spot on when you mention the “mismanagement”. Most Greek governments (starting with the current PM’s father back in the ‘80s) have been not only embezzling state funds, but also mismanaging resources, and, after Greece joined the Eurozone, lying to the rest of the EU about the state of the economy.
2. This “under the carpet” logic has permeated the society: Greeks are out in the street drinking coffee (for 3 or more euros a piece) while the country is going to the dogs. Every Greek has a brand new car, the average family has 3 TV sets, a Filippino to do the laundry and an Albanian handyman. The average Greek man supports 3 Russian mistresses and several illegitimate children, officially has two jobs, unofficially 3, but only works around 20h a week, goes to the bouzoukia every Saturday night where he’ll spend at least 200 euros, and gives his kids more pocket money per week than an American child will see in a month. And this is the real problem. Greeks, on all levels, keep spending as if they’ve won the lottery, and when the money runs out, they just go and get a loan, or simply get themselves another credit card. And it’s accepted in the society that “this is what everybody does”.
3. Tax evasion is the norm, to the extend where there are laws that accept it as a fact. If all Greeks paid their taxes (I believe the evasion it’s something like 18BE/year or something), the problem would be solved overnight.
4. Now as far as the riots are concerned: everyone could see it coming, and it was only a matter of time. This is a country where people have a fistfight over who had right of way, and where a football referee was hospitalised in 2003 for giving a penalty that was actually uncontested, but the logic was that “he shouldn’t have given it so late in the game, even if it was a penalty”. This is a country where I was told by judges that, in order to solve my legal problem, the prudent thing to do would be to hire hitmen, and where the Supreme Court can be easily bribed to cover up a crime. A country where policemen, even when they are not corrupt (and they’ve come a long way) are too scared to intervene, and where riots and fires are now a “tradition”. When a syndicate or any group of people want something, the normal thing to do is go on strike, demontrate in the street, and burn a few cars (hence the rise in car sales despite the crisis). A country where even pensioners and the Single Mothers’ Union got into violent clashes with the police, and where there is a union strike even for a journalist that got fired from a private radio station (something unthinkable in any capitalist economy). And where lawyers went on a 2-year-strike, and even policemen strike!
No wonder then that, sooner or later, and with goverments (not this current one, but all the ones before) not simply mishandling, but outright stealing money, raising taxes that nobody pays, lowering salaries, firing people who are opposed to the governing party and hiring those who support them instead, and general corruption in every level of society, we reached this point. It will only get worse. Especially when racism trully kicks in.
