Now let me say something about infrastructure. It seems to me that infrastructure spending is a very important and good way of stimulating the economy. The challenge will be to do it quickly, to find projects that can be done that have a high social return that also can be done with the greatest speed possible.

I am concerned, as I'm sure many of you are, that these jobs not simply go to high skilled people who are already professions or to white male construction workers. I have nothing against white male construction workers. I'm just saying that there are a lot of other people who have needs as well. And therefore, in my remarks I have suggested to you, and I'm certainly happy to talk about it more, ways in which the money can be -- criteria can be set so that they money does go to others: the long term unemployed, minorities, women, people who are not necessarily construction workers or high-skilled professionals.

Finally, let me say this. We've never been here before. There is not an obvious template. There is not a clear direction.

Anybody who tells you they know exactly what to do doesn't know what they're talking about. We are going to have to approach this in the spirit of experimentation. We have to keep an eye on what works and get rid of what doesn't work as fast as possible.
