Interesting article by Thomas Friedman (The World is Flat) on an increased need in the US for concentration in infrastructure. In particular he focuses on how China built up massive infrastructural improvements while US infrasture falls behind.

I don't know which presidential candidate would do a better job, but his point is certainly well taken! One thing I have to wonder though is how much cheaper and easier it is to build infrastructure from scratch rather than fixing or vastly improving infrastructure that is already in place. For example, if you already have a six lane highway that is well used, it's costly to improve it in that you have to divert a massive amount of traffic to do so. On the other hand, if the highway isn't there yet, you don't have to worry about as many indirect costs of construction.
