My roommate Kriston Capps is having some difficulty explaining to his parents why the Fair Tax is not, in fact, fair. I think the talking point you want to hit here has to do with the effects of excluding savings and investment from taxation. Under the fair tax, Paris Hilton's maid winds up paying a bigger proportion of her income in taxes than does Paris Hilton. People who can afford giant mansions aren't going to pay 30 percent on that, people who can afford full-tuition for their kids at fancy private universities aren't going to pay 30 percent on that, people aren't going to pay 30 percent on their European vacations, they're not paying 30 percent on what they pay their maid or their gardner.
But ordinary people are going to see the price of everything they buy at the grocery store go up.
