"Joel Kotkin, an urbanologist based in California, recently compiled a list for Forbes magazine of the best cities for job creation over the past decade. Among those with more than 450,000 jobs, the top five spots went to the five main Texaplex cities. A study by the Brookings Institution in June came up with very similar results. Mr Kotkin particularly admires Houston, which he calls a perfect example of an “opportunity city”—a place with lots of jobs, lots of cheap housing and a welcoming attitude to newcomers."
