Yeah, I can't imagine somebody arguing in good faith that a flat tax is fair unless they are completely oblivious to the concept of the diminishing marginal utility of income.
A relatively high 'flat tax' might be palatable to the electorate as long as the first $85,000, give or take, was completely tax-free. People would only have to contribute once their own needs are met and they actually have something left over to contribute.
