What shall we learn from this financial crisis
NOTHING.
We, humans, are greedy. This is our nature. We want more and more. Finance is a way to get more. We always run for an easier way to earn money.
And we will always do that. Utopian societies are …. utopic. I think the greed is deeply embedded in our genome, and we always look to the financial aspect of our life. As comparison, we want to find a way to check all 5 levels of Maslow Pyramid. Money help us check all 5 levels. 
So, we will not learn anything from this financial crisis. 99% of humans are plain stupid. They are only interesting in short term and in their life only. They don’t give a damn on environment (until they are hardly hit), in financial slavery, in laws that are not affect them directly, in things that are not sustainable,… So they will look further for ways to make profit. And profit is not a zero sum game during a year. It is, however on longer periods, when markets are regulating themselves
We will keep running for profit. We will run further into crisis after crisis. Because this is who we are. Stupid, egoistic, self-center individuals. The perfect viruses for this planet. We consume every resource we have in our disposal.
So, good luck to us all…
Be smart. At least you can learn from this crisis is learn when it wil be the next downturn, and not to be so greedy, when you should mark up your profits at the next buble
