Daniel Altman's proposal for a tax on wealth over $1 million. He makes the case for taxing wealth not incomes to reduce inequality as this is where the situation in terms of inequality has worsened for the U.S. in recent decades. To support this proposal Altman cites the change in the U.S. Ginni coefficient, which measures inequality. The Ginni coefficient is anumber from 0 to 100 which goes up with higher income inequality. From the late 70's to the 1990's, the Cnesus Bureau showed this to be in the low 40's. By 1992 the Ginni coefficient went up to the mid-70's, according to the Federal Reserve data. It increased to about 80 in 2010. In 1992 the top 10% in the U.S. population controlled 20 times the wealth of the bottom 50%. By 2010 this figure triples to 65 times. and the graduated income tax even if it redistributes a small share of the wealth does little to affect the trend of wealth extremes from building up and threatening the social fabric of America, reducing mobility and opportunities for the bottom 50% to unprecedented levels since the 1950's. ...
