The Dilemma Market-State

Some commentators and policy-makers think that financial markets, as we have known them so far, should be saved.
But it is exactly the excessive importance of the financial market and high private and public debts to have caused this international crisis.
The ideology of deregulation, has failed.
Paul Krugman, noble price of Economics, is one of the most important supporters of the idea that the financial system should be changed (The Market Mystique).
The State, no longer "the problem", should regulate the market.
However, people who are in charge and should set-up the rules, are the ones who have worked for financial institutions which have caused the disaster. This article by Michael Hirsh, ‘Government Sachs’ Is Back, is very enlightening and clearly explains how Goldman Sachs and other big Companies have always influenced the American Government policies and now one of their man is Treasury Secretary. Is he, with his team, going to change something?
