are we going to open all the loopholes back up as well?
No, but we won't go back to the 91% top rate.
there are 3 goals to a tax system.
Says who?
Actually, warping choices is an excellent thing for a tax system to do.
In CA, you don't pay sales tax when you buy unprepared food, but you do when you buy a new TV or a restaurant dinner.
When you donate to a non-profit charity, you get a tax deduction.
When you invest in hiring in an 'Enterprise Zone' with an especially high rate of poverty and problems and that helps society, you can get a tax credit.
There's the 'R&D tax credit' for corporations.
Cigarette taxes discourage smoking.
Good tax incentives are a great tool for government to help society. Of course, corrupt tax incentives are bad.
that it be fair (which is subdivided into people with the same amount of whatever being taxed pay the same tax and that people with more of whatever being taxed pay more tax than people with less). the income tax system is a failure at all 3 (mostly due to the intentional warping of choices the tax system encourages)
Well, fair is an arguable definition, but even using yours, last I checked our earned income tax fits your definition, with progressively higher tiers.
Now, passive versus earned income, you can argue unfair - but you did say 'the same amount of whatever' and some would argue they're two different things.
I'd have a different definition of 'what makes a good tax system'. Incent things good for society, productive things; raise enough to pay the bills, or not far off.
They should be distributed so that 'a rising tide lifts all boats' again.
