The Economist has a great article on the US infrastructure,
Life in the slow lane. Contrary to the OP, the article points out several things.
One, the world is passing the US by regarding the state of this country's infrastructure. The US rates 23rd in the world in infrastructure quality.
"In 2005 Congress established the National Surface Transportation Policy and Revenue Study Commission. In 2008 the commission reckoned that America needed at least $255 billion per year in transport spending over the next half-century to keep the system in good repair and make the needed upgrades. Current spending falls 60% short of that amount."
"At the state and local level transport budgets will remain tight while unemployment is high. With luck, this pressure could spark a wave of innovative planning focused on improving the return on infrastructure spending. The question in Washington, apart from how to escape the city on traffic-choked Friday afternoons, is whether political leaders are capable of building on these ideas. The early signs are not encouraging.
Mr Obama is thinking big. His 2012 budget proposal contains $556 billion for transport, to be spent over six years. But his administration has declined to explain where the money will come from. Without new funding, some Democratic leaders have warned, a new, six-year transport bill will have to trim annual highway spending by about a third to keep up with falling petrol-tax revenues. But Republicans are increasingly sceptical of any new infrastructure spending. Party leaders have taken to using inverted commas around the word investment when Democrats apply it to infrastructure.
Roads, bridges and railways used to be neutral ground on which the parties could come together to support the countrys growth. But as politics has become more bitter, public works have been neglected. If the gridlock choking Washington finds its way to Americas statehouses too, then the American economy risks grinding to a standstill."
America's transport infrastructure: Life in the slow lane | The Economist
I think everyone should read this article,
The Economist is a very conservative economic resource and is realistic in it's thinking.
The bottom-line, the US has NOT taken care of it's infrastructure. Funding for the US infrastructure is at historical lows. Not having a sound and up-to-date infrastructure costs lives. Not having a up-to-date infrastructure hurts the US economy and not solving this problem"
the American economy risks grinding to a standstill".
