    • President Obama's (and Others') Clueless Love of Chinese Infrastructure Spending

      Over the last few weeks, President Obama has traveled the country campaigning on the taxpayers' dime trying to sell parts of his Big Jobs Plan.  In order to sell a chunk of that plan - a massive new government spending spree on domestic infrastructure - Obama last week repeatedly cited China's infrastructure spending as the prime example of how the United States is desperately falling behind and needs to catch up:

    • Thousands Of Bridges Are One Freak Accident Away From Collapse

      SEATTLE (AP) — Thousands of bridges around the U.S. may be one freak accident or mistake away from collapse, even if the spans are deemed structurally sound.

    • Washington bridge collapse shows aging U.S. infrastructure has improved little since 2007 Minnesota tragedy

      The bridge collapse on Interstate 5 north of Seattle this week highlighted the nation’s aging infrastructure and the lack of significant improvements in the six years since 13 people died when a Minnesota span fell. Investigators haven’t determined what caused the failure of a section of the bridge over the Skagit River in Mount Vernon, Washington, after a truck struck some of its steel girders. The collapse followed the commitment of $48.1 billion in U.S. economic-stimulus funds for transportation projects since 2009.

    • Debunking US Politicians' China Infrastructure Love... Again

      US politicians, particularly Democrats, have been enamored with China's massive infrastructure spending for years now.  I've already taken a few swipes at this misguided affection, but it seems that it - and the underlying assumption that massive new spending on US infrastructure will boost jobs and jumpstart the flagging economy - will again play a prominent role in the 2012 elections.  For example, Massachussetts Senate candidate and Democratic National Convention headliner

    • 17 Major US Bridges That Need To Be Fixed Right Away

      In this year's State of The Union, one of President Obama's proposals was to immediately build a public private partnership to fix the nearly 70,000 structurally deficient bridges in the United States.

    • America's Broadband Opportunity: Today the administration is freeing up a chunk of new wireless spectrum

      [NOTE: This post is a reprint of an Op-Ed that ran in the Wall Street Journal on November 15, 2010]By GARY LOCKE and LARRY SUMMERSRarely is there an opportunity to simultaneously catalyze private-sector investment, help create hundreds of thousands of new jobs, and increase much needed government revenue. President Obama is seizing just such an opportunity with his commitment to nearly double the amount of available commercial wireless spectrum over the next 10 years. Today, the Department of Commerce's National Telecommunications and Information Administration (NTIA) will take the first step by announcing a plan to free up 115 megahertz (MHz) of spectrum.Spectrum is fast becoming a pillar of America's digital infrastructure. It has enabled the mobile broadband revolution. All of our smart phones, netbooks, and the "apps" they support depend on the availability of wireless spectrum.But while demand for America's spectrum resources is increasing at rapid rates—the amount of information flowing over some wireless networks is growing at over 250% per year—there has not been a corresponding increase in supply. This congestion has led to more dropped calls and slower data rates.
