I had a bad day last Friday, but it was an all-too-typical day for America.

It actually started well, on Kau Sai Chau, an island off Hong Kong, where I stood on a rocky hilltop overlooking the South China Sea and talked to my wife back in Maryland, static-free, using a friend’s Chinese cellphone. A few hours later, I took off from Hong Kong’s ultramodern airport after riding out there from downtown on a sleek high-speed train  with wireless connectivity that was so good I was able to surf the Web the whole way on my laptop.

Landing at Kennedy Airport from Hong Kong was, as I’ve argued before, like going from the Jetsons to the Flintstones. The ugly, low-ceilinged arrival hall was cramped, and using a luggage cart cost $3. (Couldn’t we at least supply foreign visitors with a free luggage cart, like other major airports in the world?) As I looked around at this dingy room, it reminded of somewhere I had been before. Then I remembered: It was the luggage hall in the old Hong Kong Kai Tak Airport. It closed in 1998.

The next day I went to Penn Station, where the escalators down to the tracks are so narrow that they seem to have been designed before suitcases were invented. The disgusting track-side platforms apparently have not been cleaned since World War II. I took the Acela, America’s sorry excuse for a bullet train, from New York to Washington. Along the way, I tried to use my cellphone to conduct an interview and my conversation was interrupted by three dropped calls within one 15-minute span.

All I could think to myself was: If we’re so smart, why are other people living so much better than us? What has become of our infrastructure, which is so crucial to productivity? Back home, I was greeted by the news that General Motors was being bailed out  that’s the G.M. that Fortune magazine just noted “lost more than $72 billion in the past four years, and yet you can count on one hand the number of executives who have been reassigned or lost their job.”
