Why should the service provider (hint small businessman) get what he gets now, and the wage earner gets his pay now plus his FICA taxes plus his income taxes?
Do you agree that this would put the business owner (who you say should get the same takehome as before the FairTax) at a relative disadvantage vs the hundred million wage earners who are expecting to get their whole check (15-25% more income than before the FairTax)?
The small businessman gets his whole paycheck now. He just writes a check quarterly and another at the end of the year for both taxes and FICA. The wage earner is at no advantage. What are you talking about?
