If you want to support fair tax for legitimate reasons, that is great. There are many positive aspects of the plan. Personally, I am in the home building business, and I think a 30% tax on new homes will destroy the new home industry. I also don't like the idea that it is a tax on my accumulated wealth that I already paid taxes on. If someone wants to make an honest case for the fairtax, that's fine with me. But when they put out propaganda like the fairtax calculator or many of their other exaggerations, I will call them on it.
I actually think it may be neutral for the home building industry.
Although the tax would add a large bite to the selling cost, people will also be able to qualify with their full income. THe lack of tax withholding will add thousands of dollars to the monthly take home pay of most families.
I have not dissected all the points of the plan, so I do not propose to be an expert, but the home industry would have to be protected in some way as it is the backbone of our economy.
As for taxing dollars we have already been taxed on, that happens all the time under the current system as well. The government will get its bite no matter waht, but at least the taxes can be fair, not "progressive", and up front. I think everyone should get their full income and have to write a check for the taxes, so they can see exactly what they are giving to the government
