The IRS says that approximately 16% of all wage earners NEVER file taxes. They simply do not pay income taxes.
Illegals do not pay income tax. Criminals do not pay income tax. The nonworking wealthy do not pay income tax.
Under the Fair Tax, everyone pays taxes. It is still proportionate because obviously people who make more spend more, thus paying more than those who spend less.
Read the book.
That belies the Fair Taxers' argument that all retail prices have embedded income tax of about the 23% level. All these groups pay embedded income taxes when they spend their money.
So which is it? These people escape taxation, or we all pay embedded taxes? The FTers are smoke and mirrors dissemblers.
