If you’re talking about the fairtax site’s calculator - it is poorly designed in that you have to FIRST go near the end to fix your assumptions - then run the numbers - for it to make sense.
I cannot claim to be an expert om the FairTax.
May I just ask you this...
If one man is single, has no children and makes $75,000 a year... will he pay more, less or equal taxes to a man who has a wife & 2 children who makes the same amount?
Thanks.
