Jennifer Rubin downplays the amount of revenue that can be raised from new taxes on high earners. Jonathan Cohn admits that taxing the rich won't solve all of our debt problems, but he thinks Rubin goes too far:
Are there other reasons to oppose raising taxes on the wealthy? Sure. You could argue it will slow the economy or that it's simply unfair. But evidence for the former position is thin and the popular support for the latter is even thinner. I presume that's why conservatives spend so much time trying to convince us that taxes on the wealthy simply wouldn't have an impact.
We've been over this territory before.
