| Some people, such as our German friends, want to retain only one criterion and to abandon progressivity. |
| Increase the progressivity of the federal income tax, and finance Medicare through increased sin taxes, gas taxes, and general revenue. |
| The principle behind progressivity is that people need an average amount of money for their basic needs such as food and shelter. |
| Thereafter it increases as a percentage of GDP, reflecting the progressivity of the income tax system. |
| Clearly, the estate tax is at an extreme of progressivity, since the vast majority of taxpayers do not pay it at all. |
| We could debate how to deal with progressivity where all of our points are concerned. |
