As we have seen thus far, the service sector dominates developed countries such as the United States, but within this sector is a wide range in terms of wages. Restaurant and retail sales workers face low wages and limited opportunities for advancement, while those in business and finance, computer and math, and arts and media occupations enjoy higher wages and ample room for professional development. The subsegment of professionals that are in the creative class enjoy even more opportunity for good wages, professional growth, and exciting lives in culturally diverse urban areas.
