10% of a dollar is $0.10. Doesn't matter if you have 10,000 dollars or 100,000 dollars. Don't compare apple to oranges by applying what is bought to the income of the buyer. You just want to punish people that have more.
Another good way of explaining your "flat" tax is "From each according to his means , to each according to his needs". Sound familiar?

*sigh*
You need to look at it as a percent of your income. Those who make more pay a less percent of their income, per item, than those who make less.
People making less are taxed at a higher percent rate of their income.
The Fair Tax is regressive.
