This would benefit the poor much more than having an income tax. Income tax begins when a person earns more than $11k per year. If a national sales tax was implemented, they would save much more annually. Considering many states don't put a sales tax on food or other necessities, this will help the poor (or everyone really). I would like to see a luxury tax on items that the rich would go for: yachts, planes, cars over $40k, homes over $300k, or any other luxury item not necessary. This should be seriously considered and debated.
