Personally, I don't care if the wealthy pay higher taxes. In the recent election, 8/10 of the wealthiest counties in the US voted for President Obama, and his stance on tax rates was clear. If those voters are willing to pay higher taxes, I'm fine with that.
But what I really hate is the class warfare and populist messages driving fiscal policy. With the threshold at $250k, the tax hikes would still only bring in enough added revenue to cover 8 days of federal spending. And "fair share"? The top 5% pay 40% of the federal income taxes collected. In order to generate the kind of revenues that would make a significant impact on the deficit, taxes would have to go up across the board, which in turn would lead to an economic slow down.
