All of this is so strange. How is not raising someone's taxes a "huge giveaway"? Who is "we" exactly? Since when is whether someone can afford it the rule for choosing how much to tax (well, I'm given to believe that's how taxes were collected back in the middle ages)? How is the fact that a person may not do exactly what 1960s Keynesian economics wants them to do with their money grounds for taking their money?
Look, I am not disputing that they can "afford" to pay the tax or that those stingy bastards probably will just save the money if "we" let them keep it.
But I am pretty sure that the top 1% of earners are already paying over 40% of the total Federal income taxes, even at the "giveaway" Bush rates. Over 40% of households pay no Federal income taxes at all. "We" are also popping the rich in other areas of taxation besides their top income tax brackets.
On top of all this, the fact remains that taxing "the rich" will not come close to balancing the Federal budget.
On this issue, the progressive blogosphere seems more like a herd of villagers with pitchforks and torches than a group of sophisticated intellectuals.
