A new Era for capitalism?

Looking at the current financial collapse one must agree that greed and irresponsible conducts have taken place in a massive scale in the Past. What is done cannot be changed, but we must not forget and more importantly: we must learn from our mistakes. I have just read an article witch is very interesting from professor Luigi Zingales: http://faculty.chicagogsb.edu/luigi.zingales/Why_Paulson_is_wrong.pdf

It is obvious for me and for any tax payer that the underlying principle of this article is correct and that we must start to view the "investment banking business" separately from the "deposit banking business" which means:

1. The ones that had irresponsible conducts in the past will suffer the consequences;
2. Investors (pension funds, private investors, etc) MUST understand that in the future their reward for having liquidity will become lower and less risky at the same time;
3. A more concentrated market in the financial sector;
4. A more conservative investment strategy from individuals, companies and governments due to the adversity that the financial institutions will have for high risk operations;
5. An effective and controlled mechanism of risk classification within banks (maybe managed and audited by an external institution?

In fact we must agree with Luigi Zingales: "The time has come to save capitalism from the capitalists."
