I don't understand what you're asking for because I don't understand the utility of the answer so I thought that if you gave an answer, I could work backwards.
You're the one that stepped up and thought you'd give answering DD's question a shot. If you simply cannot provide an answer, then that's fine. It's a complicated question that some folks are content with saying "more" or "less" and leaving it at that, in spite of the fact that they never really provided any kind of an answer.
Again, "no, u" isn't an answer.
That's not an unreasonable request unless you don't have an answer.
I gave the oft hated reason poor people get tax rebates because I thought it illustrated the fact that Ronald Reagan signed a bill that not only exempted poors from paying taxes but actually incentivized work via direct transfer payments.
Which is all well and good, but has zero to do with the question: "How much should the rich pay in taxes?"
So you don't want that. That's dodging. OK. What do you want Bob? What does an answer look like in your mind? I've never shied away from a conversation and typically write about a thousand words too many when I do. So why is it difficult to get an answer to your own question?
There are a couple of ways you could answer this - and it would depend on your individual philosophy as to how taxes should be assessed and paid. You could say that people should pay X% per year based on $Y of income. X% per year based off of $Y Net Worth. You could use either (or both) of those on some sort of sliding-scale (X% for the first $Y, 2X% for the next $2Y, etc.) You could say folks should pay $Y per-head flat rate. You could go with a consumption-based tax where it's X% per $Y spent. It could be a production-tax, like a VAT Tax. There's all kinds of possibilities. It comes down to the question DD asked - "How much should the rich pay in taxes?"
It's a very complicated question - and I don't purpose to have the exact answer (though I do have a few thoughts that feed into the answer)... but then, I never asked for the answer. DD did. And, about a month ago, someone else asked the same question, and a certain someone on this forum jumped down that person's throat for asking the question because blah, blah, trolling, blah, blah, blah. I was just curious if that same someone was going to speak up when DD asked the same question.
By the by, since you seem to be stuck on Regan - when Regan's tax levels where in place, what was Federal spending per-capita then (adjusted for inflation) and what is Federal spending per-capita now?
