What "false assumptions" ? If you disagree with my assumptions, then provide a counter-argument, with independent backup.
What numbers did I try to "skew" ?
"...the two examples were about even when clearly, even with your false assumptions favoring the Fairtax, they weren't."
When two examples fall within 5% of each other, that is pretty "even", in my book. Total purchasing power under the income tax was $3,408,000 and under FairTax $3,248,000. A difference of 4.7% and that is even assuming ALL spending was on taxable items. A little time traveling in Canada, or taking art classes, or buying used vehicles, antiques, etc. might even have erased that small difference. On top of that, I stayed completely away from any assumed decrease in prices, even though Rob has previously mentioned he would expect an 8% drop.
As far as being "snippy" with FA, I would bet he had a much larger difference than 5% in mind when he made those dogmatic comments. His refusal to give any particulars about an example that might prove his point just showed it was nothing more than an assumption. He'd never run any numbers, or he'd have been able to provide them.
"You say that now after you know ..." Actually, last week another poster named Polybius and I went through another example, and I asked all the same questions. The idea that a valid comparison is going to be complex is not news to anybody but you.
