You just can't satirise the material on National Review Online anymore --
Cliff, I actually think it's exactly the form of tyranny the Founders feared. As an increasingly sizable majority pays no taxes, the minority's representation becomes ever more illusory. The minority will be taxed, its property rights will be eroded, and it will have no meaningful say in the matter. A tyrant is a tyrant, whether he's a king or a block-voting majority of dependents.
It's likely a waste of time trying to make a serious point about something like that, but the serious point is that lots of people in America don't pay much in terms of income or wealth taxes because they don't have much income. If you want participatory democracy, you need a participatory economy.
