First, welcome to the forum. As to the topic...
I would enjoy an actual discussion about the issue based on merit but most people tend to shy away from such challenges... Let's find out if you will as well.
Thanks for the welcome GenSeneca. I was hoping to avoid getting too immersed in statistical arguments, because ultimately I've seen statistics that correspond with your argument and statistics that refute it. So engaging in the argument at this level is going to require more research and will most likely end unresolved because of conflicting data, but that doesn't mean it isn't worth engaging in for the sake of better understanding the issue.
Another complications is that both proponents and detractors of the Buffet Rule tend to respond to argument on a number of different levels, and so it is often the case that a statistical reference is made to refute a moral objection and vice versa. What you end up getting, then, is "it doesn't matter if that would benefit x% because it's immoral", "but it's more immoral to adhere to x sort of policies", "well, no - because statistics show...", etc.
My primary argument is philosophical. I don't take issue with people keeping what they earn. I take issue with the notion that any one of us earns what we "earn", for a number of reasons. It would spawn a novel if we were to debate on this abstract a level. For example, if reality is socially constructed, decision making inherently flawed, market decisions constrained by cognitive bias and incomplete information etc, than free will is inherently restrained by social and neurological forces beyond our control. That is a gross simplification of one tiny aspect of the foundation of my belief system.
But it alone seriously impacts this debate, at least insofar as conceptions of value and ownership and the morality of taxation is concerned.
And it becomes hard to debate because people tend to associate some of the conclusions I draw with social philosophies inconsistent with my own. Once they have done that, everything I argue is understood in a different and inaccurate context and I am constantly having to correct for these assumptions. That said, my personal philosophies are by no means sacred. I love hearing arguments against them, but it's hard because my philosophy derives more from social/neuro/behavioral science than it does from political or economic philosophy, and people aren't nearly as familiar with the relevant research in those fields.
But the bottom line is, we're unlikely to agree on the morality of the argument, and it would be exhaustive to pursue that line of argument at this point.
So these are the complications in this style of debate. At some point I'll get into some of the material I mentioned above in a different thread. But for now, you're absolutely correct in noticing that I used 'if' to qualify my statement. So if you want to put all 'moral' issues aside (for now) and just discuss the economics of this buffet rule then I'm game. Let's get to it. If this rule will do nothing to benefit the nation's economy and the people it is intended to help (we'll have to qualify who, exactly, that is) than I will absolutely change my position.
But if we establish that the Buffet Rule will likely benefit the economy, and provide relief (or at least, not burden) for lower-income Americans (which we'll have to quantify), then we can move on to discuss whether we ought to be supporting the poor or taxing the rich and so on. But first lets stick to whether or not the Buffet Rule will function like Obama claims it will.
How about it?
I will add that you make good points, and I don't mean to dismiss them by not addressing. I did want to say a few things, but if we don't approach this systematically, then we probably aren't going to accomplish very much. Who knows if we'll be able to maintain this, but I'm willing to try.
