I read the tone of your post as angry disagreement, you seem to be agreeing with me? My point was >I think what we're really upset about when it comes to rich people making a lot of money through investments is not that interest isn't taxed more, but rather that they had such a high (non-investment) income in the first place. And people having different levels of income is definitely at the heart of your objection. Rich people tend to have more flexibility with regard to their ability to choose future consumption over current. The problem we have with that is that they're rich enough to do that, not that they are making that tradeoff. The tradeoff is inherently benign and should not be discouraged through taxation.
