Book excerpt: This book looks systematically at the extent to which Jews, women, African Americans, Latinos, Asians and gay men and lesbians have entered the higher circles of power that constituted what sociologist C. Wright Mills called 'the power elite.' It examines why and how the power elite has diversified, the pathways taken by those who have entered the power elite, and the effect this diversification has had on the way power works in the United States.
