End special treatment for Capital Gains and tax that income at the same rate as the wages, salaries and tips.
Why is this important?
Capital Gains, the bulk of income for the 1%, is taxed at 15%, while income from work is taxed at 15-35% PLUS 7.65% payroll tax on roughly the first $100,000. This means the marginal tax rate for the 99% is roughly 22-42%. Ending the special treatment for Capital Gains and taxing it at the same rate as wages, salaries and tips would bring Warren Buffet's tax rate in line with the rest of us.
