The professional class, also called the upper middle class, consists mostly of highly educated white collar salaried professionals, whose work is largely self-directed. In 2005, these household incomes commonly exceed $100,000 per year.
Economist Gary Burtless of Brookings Institution indicates that the middle class encompasses from one-half the median income to twice the median income. This would make the middle class income range $25,117 to $100,466.
