This is a complicated situation and somewhat frightening. To Bail Out or not? What we see in Greece is what could have been the situation in the US recently (within the last 2 years)and in fact was exactly the case. You now have Greeks acting Irrationally and clashing with the Police, a relatively stable Democracy flirting with Self Destruction. Ironically the causes(Taxes and Economy) are fairly similar to the US Tea Party concerns, although more extreme and in the Tea Party's defense it is more concerned with avoiding the Greek situation, albeit not actually being inspired by the Greek situation. Greece has merely conveniently occurred showing the precariousness of National Debt/Deficit and how it relates to Economy.
What is causing the Greek irrationality? A crappy Reality. That being the convergence of Bad Economic Times with past Bad Fiscal/Economic Policy that now puts the National Economy at risk of total collapse. Now to avoid Bankruptcy the Government has to implement Austere measures and a combination of drastic Cuts in Services/Programs and drastic Increases in Taxes. It's a double whammy that would piss any Sane person off. However, that's the Reality of it and there's nothing the Greek Government can do about it now. They certainly could have avoided it, but that possibility passed by Years ago.
Should Greece be Bailed out? I think, Yes. Not just to help Greece stabilize and deal with Domestic upheaval, but also because(as noted in Thread)there's a line up of other Nations heading toward the same fate. It's one thing to have 1 Nation Fail and possibly descend into violence, but quite another to have a half dozen or so likely joining into that as well. We're not discussing inconsequential Nations here(sorry for the terminology) either, but some of the Wealthier Nations of the World whose Meltdowns ultimately spread beyond their Borders. We've been down this path before and as we learned it leads to things such as Communism and Fascism when People have become desperate enough.
It may seem expensive and I'm sure many will cling to their Black/White views regarding it, but we all know that eventually the Economy will recover and that we can get past these difficulties, in fact that seems one of the prime reasons some people would oppose Bailout. So my point is, since that's the case, it's best to smooth over potential situations that can bring the Global Economy Down, if the ability to do so exists. Let them get by for now and when the danger has passed, they'll be better able to correct their situation.
