Short answer: no. Longer answer: depends on what you mean by “world-class.” Mercer just released its ranking of livable cities. Dallas, a new addition, came in at No. 61. Other U.S. cities on the list:
31. Honolulu is the city in the United States with the highest quality of living
32. San Francisco
37. Boston
45. Chicago and Washington (tie)
49. New York, the base city for the ranking
55. Philadelphia
61. Dallas
