Do you support or oppose the Fair Tax?

Do you agree or disagree that the USA should get rid of the income tax and create a national sales tax? The poor consume less so naturally they would pay less, but with the fair tax they would be able to keep their entire paycheck. It would save time & money in the government by eliminating tax evasion and freeing up the legal system. The Gov. would save billions by not having to process income taxes, and it would eliminate payroll taxes so companies would have more money to spend boosting productivity, while people will have more money to spend which in turn creates more jobs.
