Financial crisis is a symptom, the underlying economic ailment is what's hurting the society.
When people are hurting, there are behavioral responses that is human nature, which didn't change much over the recorded history.
If we look back at the Great Depression, and the ensuing tariff war, and the following competition for colonies, and the resulting militarism and fascism, I wonder what's in the store down the road for the world? The world is so interconnected today it is hard to imagine we will take the same paths our grandparents did. But given the rise of nationalism worldwide and the recent 2008 financial crisis, the deja vu cannot be ignored.
