That's pretty much what I used to think. But then I started hearing Jerry Brown talking about a flat tax, and I began to see that there are many ways of writing a flat tax. Just as there could be many ways of writing a VAT, and when I set my own mind to it, I had all kinds of fun deciding what sort of percentages to apply to minks and mercedes.
No, Doug, I am not confusing "complexity with progressivity." I know what a progressive tax system is. But, I think you are oversimplifying the nature of the proposals that have actually been mooted. On the other hand, I would grant you that the overwhelming (I'd even say inevitable) probability is that the character of a flat tax enacted by this society would be regressive. And, I think you're probably right that at SOME cut-off point, EVERY flat tax becomes regressive, with say billionaires not paying as much as millionaires.
The major advantage of a flat tax written by progressives would be to exempt completely the lower 80% of the income scale. Remember, progressives would totally eliminate the defense budget first. I mean, we won't need that much money after we give up the army, will we?
You're the expert, Doug, and I should probably shut my big mouth. But, the impression I get from many people I meet is that they KNOW what a progressive tax is, and they want a progressive flat tax. I don't see what good it will do for you to explain that there is no such thing, but you probably know best.
