The growing municipality of Houston positions as the fourth greatest metro run in the United States, ranking behind New York, Los Angeles, and Chicago. More that half of Fortune 500 energy companies are headquartered here, giving Houston an unrivaled advantage in the overall energy industry. Marcus Hiles has been optimistic of this development of Houston. A great deal of Houston’s employment and advancement has been driven by the energy business. The expansion of the Panama Canal also adds up to the strategic advantage of the city, where industrial giants attempt to beat West Coast in the acquiring of foreign goods. The Port of Houston is the second busiest port in the United States, closely competing with Port of Los Angeles for trade and jobs. Likewise, the Texas Medical Center, sitting just three miles south of downtown, has over 100,000 representatives and includes facilities such as hospitals, research organizations, pharmacy schools, nursing programs and a dental school.
