percentage of americans who are millionaires
In the United States, approximately 7% of households are millionaires.[7] A 2010 study argues that millionaires (those in the top 1% of earners) pay approximately 40% of all taxes in the United States.[4] According to the book The Millionaire Next Door, only 20% of millionaires inherited their wealth.
A third of the wealthy â1 percentâ in America are entrepreneurs or managers of nonfinancial businesses. Nearly 16 percent are doctors or other medical professionals. Lawyers made up slightly more than 8 percent, and engineers, scientists, and computer professionals another 6.6 percent.
