Well about five members fo the public died. It will be worse than that. The government will lose control. Not that this is a bad thing. They are after all the people that created this mess.
If the Euro collapses, aside from the economic turmoil, I think the most important ramification is that the countries of Europe will have avoided losing their sovereignty to the nascent Euro-empire that the bankers are trying to form. The alternative to Euro collapse is probably that the Eurocrats succeed in using the upcoming crises to scare everyone in Europe into issuing Eurobonds backed by some sort of central fiscal Euro government. If this happens, you can kiss representative democracy in Europe goodbye.
To be honest. Democracy does not exist here anyway. They do what they want and are not held to account. The reality is that if they infringe on human rights too much they will riot. I think that it is more likely to fall into anarchy than anything else. Mad Max style.
