You are forgetting where and why the financial crisis started. Although in the US the financial institutions were saved by printing money in the rest of Europe the ECB controls the presses.
I don't think it is accurate to say that the 2008 financial crisis had a single cause. If you think it was the boom in sub-prime mortgage lending in the US and the resulting popularity of CDOs and CDSs how did that cause the Irish problem (insane property speculation), Iceland (asset speculation in other countries used borrowed cash), Greece (fiscal irresponsility) etc.
We forget how bank operate: they ask you to trust them with your cash and in return they promise to safeguard your capital and even give you interest a year. Well, what if their investments lose most of the money and the government cannot bail them out? They go kaput!
