I want to start here:
I don't look at any law or tax ruling in terms of benefiting/hurting the poor/rich. I look at it as is it a reasonable and consistent approach to collecting this tax. We shouldn't be able to be unfair to a group, just because they are a minority, whether that minority is rich or poor. I don't think things should be justified because they only affect a few people. Right is right, wrong is wrong.
It looks like we are coming at this from different directions. I don't think our tax laws should be designed to favor any race, religion, sex, etc. over another. But, I definitely believe that tax rates should be graduated.
We have to collect taxes to support the gov't. We should do it with the least pain. People with more income or assets should pay higher tax rates than people with less simply because they give up luxuries to pay the tax, not neccessities. For the very wealthy, they have so much money they can't spend it on normal "consumer goods" during their lifetimes, we should tax them at the highest rates.
Since I've had a higher income than most Americans, I should pay above average rates. And, people with more than me should pay even higher rates.
So the fact that this is another tax cut where most of the money would go to the very wealthy, means that it goes in the wrong direction for me.
I understand the taxing nominal investment income instead of real investment income makes our "income" tax actually two taxes. An income tax on the real income plus an asset tax driven by inflation. That's okay by me. Normal people pay many taxes - income, SS, Medicare, sales, real estate, gasoline, etc. If high wealth individuals also pay an asset tax, fine. (Especially since that is actually simpler than trying to inflation adjust all investment income.)
But be aware, for most people this would not be such a big deal for CDs overall. You have that rate compared to inflation for the year, versus a capital gain over many years. I suppose if you were in CDs for 10 years, it kinda comes out the same, though cap gains are expected to be higher than CD rates, so more impact on cap gains.
Maybe we're not understanding this the same way. Suppose Andy buys a 1 year* CD that pays 5% and credits interest annually. Bob buys a stock with no dividend, and sells it one year later for 5% more than he bought it. I think if Bob gets to adjust his gain for inflation, then Andy should get to adjust his interest the same. If the rates are 2% and 10%, I also think that both should be adjusted for inflation. If they both hold for 10 years, they should both adjust for inflation. Presumably the CD every year, as interest is paid, but the stock only at the end when the cap gain is realized.
Wouldn't that be accounted for? If I sell a bond at a gain or loss, that is a capital gain, same as a stock. Am I missing something?
Same as the CD, shouldn't I be getting my inflation adjustment every year as I'm paying taxes on my interest?
* Or 13 month, if you want to allow for the current ST vs. LT cap gains rates.
