I believe this came from an old analysis of what challenges and rewards passing the FairTax would bring and it encouraged me.
"Success will mean the passage of the single most significant domestic policy act since the income tax itself was passed in 1913... The political legacy of taking on the federal income tax is hard to overstate. It is perhaps the most reviled law in the country, and to do battle with it in a bold, sweeping fashion will be a landmark event, showing extraordinary courage and foresight, yet with limited risk. The upside is we change the country, permanently, for the better. The downside is, we fight the dragon, the dragon lives, but we fought it anyway."
