I was curious about the history of the income tax and it's "battle-tested"ness. Seems that it is a rather recent invention (at least in the graduated form) that was first started in the UK to pay for the Napoleonic wars. I'm not sure how well researched it was then, or how well it was researched before we implemented it here in the US, but I'd guess that it wasn't researched very well, if at all. FairTax has been researched a lot, and not in the creationist find data that supports my conclusions way, but in a real scientific way. I know you do your research, so I'm sure you've looked into it some already, but just thought I'd put this out there.
