Motorola runs one of the two cellphone networks in Shanghai.

The local chief is a young American named Bill Newton, who came here a few years ago with two other people and worked around the clock at first - like new immigrants, he says, who've just come to America and have nothing to do but work. Now he's managing 55 employees; he's the only American. He thinks everyone should want his job: "To be in one of the fastest growing companies in one of the fastest growing sectors of the fastest growing economy in the world - how many times in your life is that going to happen?" In the context of Shanghai, "fast growing" means, for example, that cellular phone service is growing at 140 percent a year and pager use at 170 percent a year.

Motorola's offices are in the international center west of downtown Shanghai - the modern, high-rise equivalent of the

Western enclaves where capitalists used to do business in the old days. It's got a Shangri-La luxury hotel, it's got modern offices identical to those you'd see in any big American city, it's got living quarters with purified water. Newton and I got in a taxi and took a long drive to the headquarters of the Shanghai

Post and Telecommunications Administration (PTA) - Mao Bell, if you will.

Driving in Shanghai is like shouldering your way through the crowd at an overbooked trade convention. There's never any space in front of your vehicle that is large enough to let you in, so you just ooze along with the traffic, occasionally claiming a few extra square yards of pavement when the chance presents itself. I'm hardly the first Westerner to point this out, but the density of bicycle and foot traffic is amazing. I'm tempted to write that the streets are choked with bicycles, but, of course, the opposite is true: All those bicycles are moving, and they're all carrying stuff. If the same stuff was being moved on trucks, the way it is in, say, Manhattan, then the streets would be choked.
