Taking out the same amount of tax will not have a dramatic impact on prices.
Removing the tax system collecting those income and payroll taxes from the backs of business removes the overhead costs associated with those businesses as well. That provides substantial potential for cost savings and reduction of prices out of competition for the consumer/investor's dollar.
I hate the over the top phoney claims the Fair Tax people have been making for years. Their analysis makes global warming scientist look honest.
Strange I could make a rather similar statement about those that deliberately obscure how the NRST actually impacts business overhead costs by reducing them not only by the amount of tax but the overhead associated with tax avoidence & planning, accounting and reporting, as well as the costs that government imposes on a business in audits, litigation & legal fees when the business person's crystal ball is as cloudy as the IRS and the IRS chooses to make an example of them, not to mention the fines, and penalties assessed when the IRS' tax court takes its final cut out of the hide of the hapless victim.
And that does not even begin to account for the loss of sales revenue from lowered demand for products due to higher pricing required as a consequence of the the above.
Imagine a phi beta kappa who graduates at the top of his class. Imagine the possibilities.. he could start a business that employs 200 people, or become a scientist who discovers a renewable energy source or a doctor who cures some dread disease...
but instead, he becomes a tax attorney.. and produces...
NOTHING.. what a sad loss of human capital!
