Texas now hosts more Fortune 500 companies than any other American state. They include AT&T, Dell and Texas Instruments; oil giants such as Exxon Mobil, ConocoPhillips and Valero; American, Continental and Southwest Airlines; Fluor, a huge construction firm (recently lured from California); J.C. Penney; Halliburton; and 52 others. Texas claims to have been responsible for 70% of all the net new jobs created last year in America’s 50 states, though since only a few states created any jobs at all that is not quite as astonishing as it sounds.
