The Alternative Minimum Tax was imposed in 1969 because 115 households investing in municipal bonds reportedly paid little or no federal income tax… On Jan. 1, 2013, it is set to hit 27 million more—raising an estimated $120 billion, according to the Obama 2013 budget. In 40 years, a tax on 115 households will have grown to threaten 31 million.
The personal income tax… began in 1913 with a top rate of 7% and hit only those with a taxable income of $500,000 or more. (According to the Bureau of Labor Statistics inflation calculator, that would be $11.5 million now.) Today, roughly half of American families pay the personal income tax.
