People of lower income need to use a higher percentage of their overall income on daily necessities. Many of these people are living hand to mouth during all of their paychecks on bills, rent, cloths, and food, leaving no money to put into savings. Those who make much more money can put more and more of it in savings spending a very small percentage of their overall income to survive. With only a "fair" tax some people will be paying a 23% tax on their entire income and some will be paying 23% on only 5% of their income. This is just another way to mislead the voters into voting for Fairness that is actually highly beneficial to the rich. Calling it Fair Tax doesn't make it fair.
