I've already had (and lost) one e-mail argument with Max over this, but...
Look: give me Speaker Gephardt and I would be arguing that we need more public investment, and that using surpluses to expand public investment and social insurance is better than using surpluses to pay down the debt.
That's not the choice we have: our Speaker is not named Gephardt. Our choice this year and next year is between tax cuts for the rich and debt paydowns. I wish that things were different--I could wish for that optimism of the will that would drive us to a substantial expansion of public investment in the next two years--but intellect ought to enter somewhere, and intellect should be used to make things as least pessimistic as possible.
