I've always been sceptical about the notion that the market is a person you can engage in an argument with, and that that person is an intelligent, rational, well-intentioned person: it is fantasy. We know that ... the market is subject to irrational optimism and pessimism, and is vindictive ... You're dealing with a crazy man ... Having got what he wants he will still kill you.

Wall Street banks have used the same tactic that Bush used in the war on terror - fear - and they've basically said that if you don't do what we tell you, the sky will fall. If you don't do what we tell you, it will be the end of capitalism as we know it. The failure of Lehman Brothers lent some credence to those fears.

They [free market policies] were never based on solid empirical and theoretical foundations, and even as many of these policies were being pushed, academic economists were explaining the limitations of markets for instance, whenever information is imperfect, which is to say always.

Moreover, because we chose to finance the way by borrowing, our deficits and debt has soared, and this means we have less room for maneuver, less money available to stimulate the eocnomy in the way needed.

There will come a moment when the most urgent threats posed by the credit crisis have eased and the larger task before us will be to chart a direction for the economic steps ahead. This will be a dangerous moment. Behind the debates over future policy is a debate over history-a debate over the causes of our current situation. The battle for the past will determine the battle for the present. So it's crucial to get the history straight.

When you think of policies that are going to address inequality of wealth, you have to be very thoughtful about what economists call "incidence of taxes." If most of the savings is being done by capitalists, and you tax the return on capital, then they will have less to invest. That would mean, over the long run, that the rate of interest would go up. That would therefore undo some of the intent to lower the income of capitalists.

The reason that the invisible hand often seems invisible is that it is often not there.
