Here’s what I said about this issue in another thread:
First off, can we all (on both sides) drop the insults, name-calling, and motive-assignments? Liberals didn’t categorically fail economics 101. There are very very smart honest well-intentioned economics professors who hold generally liberal views. There are very very smart honest well-intentioned economics professors who hold generally conservative views. Furthermore, the vast majority of people on both sides of this issue aren’t primary trying to maliciously injure the rich or the poor or anyone.
OK, so the question is, or at least has drifted to: is it a good idea to raise taxes on the rich to pay for government spending? (I’m talking about this in a “in 2009 America” context, rather than a purely philosophical context.)
This seems to have 2 general subquestions:
(1) is it ethical/fair to raise taxes on the rich? Is doing so “stealing” or asking them to pay an unfair burden or anything of that sort?
(2) is it economically wise to raise taxes on the rich? Will doing so generate increased revenue with drawbacks that are livable, or will it stifle economic growth and crush the US and the Chinese will use our skulls for soupbowls?
I’ll address them one at a time.
(1) I think it’s a bit tricky to talk about “fair” here, for a couple of reasons. First of all, on a purely practical matter, it’s pretty much fait accompli that we have a graduated income tax, as does basically every other country in the world. So unless you’re one of the few people who are arguing for a totally flat tax (such as Crafter Man), then it seems a bit contradictory to say that the current system is fair, but one where the top tax rate went up would not be fair. More importantly, though, even a “flat tax” is in some ways “unfair”. I mean, what about a REALLY flat tax where everyone paid $10? That would certainly be “fair”. Or a system where you paid as you go, and every single thing was done with road-use-taxes or police-use-taxes or what have you, so you actually paid for the services the government provided? That would be “fair”. My point being, “fair” is really pretty meaningless in this context.
I can come up with some things that would be UNfair: a tax system where the top marginal rate was >100%, for instance. But I don’t think “fair” is a particularly meaningful concept when comparing flat tax to graduated tax to hypothetical-super-flat-tax etc.
So let’s ignore “fair” for a second and talk about ethical. What kind of society is most “good”? Well, a useful way to think about it (I think this has a name as a rhetorical device, I saw it on an episode of The West Wing) is to try to imagine how you want society to be without knowing what rung on the ladder you’ll occupy. Sure, if I know I’m rich, I can selfishly want to lower taxes as much as possible. And if I know I’m poor I can go hogwild screwing the rich (or, to be much more fair to liberals, putting as many programs in place as possible to allow me to learn how to get richer through hard work and so forth) (particularly education) (but I digress). But if I don’t know, then what is going to give me the better average life if I’m inserted into US society somewhere at random: ultra rich rich people who can bathe in pools of champagne and poor people with no net and no health insurance and crappy educations for their kids and no housing; or slightly less rich but still super rich rich people who are stuck bathing in pools of California sparkling wine and poor people whose gets kid good educations, who have access to job training and public transport to help them get ahead, etc. Seems like an easy choice to me. (I’m quite sure that many of you reasonable conservatives are now thinking “aha, a false choice, because in the second case the economy as a whole will suck way more”. Not a prima facie ridiculous comment, and I will get to that in part…)
(2) So does taxing the rich result in economic suckage? Bluntly, no. Top income tax rates have been MUCH higher than they are now and the economy has done just fine. This is not a case where we’ve for 100’s of years had a 10% top income tax rate and some crazed nut is proposing raising it to 60% and people are genuinely concerned that that will destroy the economy. The top tax rate has been up and down and up and down and lately has been WAY down compared to where it’s mainly been, and there have been massive economic booms, and super insanely rich people, during all of those times. People can poke around in those stats and find trends, and I’ve seen them honestly argued in both directions, but it’s absolutely 100% clear that the top income tax rate can be MUCH higher than it is right now at the same time the US economy is doing absolutely utterly fine.
