Try to understand the difference between an inclusive tax and and exclusive tax. I knew this was what you were going to present and it is thoroughly discounted in #47 of link you provide. Read it and try to understand the math. Clearly, you don't undestand the difference between an inclusive tax and an exclusive tax. This is where your misunderstanding lies.
BTW, Wikipedia is a very questionable reference. Surely you've heard about all the lawsuits that have errupted because of false information being posted there?
I do understand it. Show me where I have made an erroneous statement. In post 135, you said the sales tax on a $100 item would add $23 to the item. If you still don't get it will be a $130 item after tax is added, then you are the one with the misunderstanding. And please don't confuse your ignorance with me lying. You have no idea what you are talking about. You really don't look intelligent when you namecall when it is YOU who do not understand it.

FairTax on Wikipedia offers a perfectly clear and accurate explaination of what is going on. Perhaps you should read and understand it, it would help. However, even the fairtax admits it is a 30% sales tax in the traditional concept, so whether Wikipedia is 'questionable' is mute. Fairtax.org says they convert it to an inclusive rate of 23% for comparison purposes to how income tax is calculated, but it serves to mislead lots of people, including you to believing it is a lower rate. It is a 30% sales tax as all states implement sales tax today and how virtually all people understand sales tax rates.
