At a time of massive wealth and income inequality, we need a progressive tax system in this country which is based on ability to pay. It is not acceptable that major profitable corporations have paid nothing in federal income taxes, and that corporate CEOs in this country often enjoy an effective tax rate which is lower than their secretaries. It is absurd that we lose over $100 billion a year in revenue because corporations and the wealthy stash their cash in offshore tax havens around the world. The time is long overdue for real tax reform.
