Does Dallas offer a vision of America’s future?

ASK ORDINARY Americans about Dallas and you are likely to elicit a few common responses. American-football fans will tell you that the Dallas Cowboys, once the country’s most formidable team, have seen better days. Soap-opera junkies, at least those alive in the 1980s, may reminisce about the long-running series named after the north-Texas city. The few who paid attention in history class may recall that it is where Lee Harvey Oswald shot John F. Kennedy. You will probably not hear breathless comparisons to the world’s industrial capitals.
