I bought and read Neal Boortz and Rep. John Linder (R-GA)'s new book, The FairTax Book, and was impressed for the most part. It detailed the history of the income tax and withholdings, as well as the "embedded" taxes consumers pay on everyday items.
It showed how by removing withheld taxes (ie: Social Security and income), prices will go down, plus with the FairTax of 23%, prices will remain almost constant, plus monthly "prebates" for necessities of life (food, shelter, etc.)
Overall, I think the FairTax is a good idea for both business and consumers because everyone's on a level playing field, whether you make $10,000 or $10 million. Not only that, it's a consumption tax, so if you don't want to spend your money, you're not going to be taxed. I like that :).
