One has to always ask the question: Where can one be most effective in helping shape policies? It is always difficult when you're inside because you're very constrained.

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

The attempt to minimize cost and maximize profits often interfered with our true mission in Iraq. We should have been working to get jobs for Iraqis, but the contractors found it cheaper to import Nepalese and others. This increased resentment, contributed to unemployment, and to our losing the hearts and minds of the Iraqis.

Even if Bush could be forgiven for taking America, and much of the rest of the world, to war on false pretenses, and for misrepresenting the cost of the venture, there is no excuse for how he chose to finance it. His was the first war in history paid for entirely on credit. As America went into battle, with deficits already soaring from his 2001 tax cut, Bush decided to plunge ahead with yet another round of tax "relief" for the wealthy.

If you get a flow of credit increasing, as we've seen in the last few years - that flow of credit didn't go to more wealth accumulation as we normally use the term in economics, as capital goods. What you got is an increase in bubbles of one kind or another.

There is a clear and strong link between the economy's present woes and the Iraq war. The war was at least one of the factors contributing to rising oil prices - which meant Americans were spending money on imported oil, rather than on things that would stimulate the american economy. Hiring Nepalese contractors in Iraq, moreover, doesn't stimulate the American economy in the way that building a school in America would do - and obviously doesn't have the long term benefits.

The median family income in the U.S. is lower than it was a quarter-century ago, and if people don't have income, they can't consume, and you can't have a strong economy. There's significant risk - actually it's no longer a risk - a significant likelihood of a marked slowdown not only in China, but also in a lot of other countries like Brazil, which is in recession. All of the other countries that depend on commodities, including Canada, are facing difficulties. So it's hard to see a story of a strong U.S. economy.
