Here's a chart that shows how things have changed in our tax structure since the 1960's.

The 1%ers are a little lower than their historical average, but it's not dramatic. The guys that are paying a whole lot less are the .1%ers and the .01%ers. When you see stuff like "the top tax bracket in 1960 was 70%", it doesn't mean that all of the guys paying 35% today were paying 70% back then. It meant that the ultra wealthy were paying 70%.
This is where the disconnect is when comparing the Obama increases to the top tax rate in 1960. Those rates didn't apply to the type of people making 250K today. It applied to the rich CEO guy making millions. But when you go after the guy making 250K you're hitting closer to the middle class than the ultra wealthy. Make a new bracket at the 500K or 1 million mark, and I bet you get a lot less resistance.
