Obamanomics is working- US Lost 129,000 Millionaires in 2011- Americas millionaire population declined last year for the first time since the financial crisis, according to a new report. The population of U.S. millionaire households (households with investible assets of $1 million or more) fell to 5,134,000 from 5,263,000 in 2011, according to The Boston Consulting Groups Global Wealth study. Virtually all of the growth in global millionaires came from emerging markets last year. While the United States lost nearly 130,000 millionaires, the rest of the world added 175,000 millionaires.
