This link will take you to an article with details from a Harris poll, an independent poll which shows a positive association of music with lifelong educational attainment and higher income. Nearly nine in ten people (88 percent) with post graduate degrees participated in music education. Further, 83 percent of those with incomes higher than $150,000 or more participated in music.

Respondents of the Harris Poll cite skills they learned in music as helping them in their careers today. Seventy-two percent of adults with music education agree that it equips people to be better team players in their career and nearly six in ten agree that music education has influenced their creative problem solving skills. Many also agree music education provides a disciplined approach to problem solving, a sense of organization and prepares someone to manage the tasks of their job more successfully.
