You're still ignoring the prebate.palladin9479 wrote:Anyhow it's simple. A 30% flat sales tax on a person living on borderline poverty will push them into poverty by raising the costs of goods to a level above what their capable of paying. This is because the poor person is spending 100% or near 100% of their income just to survive, they don't have much of any disposable income. As their spending 100% of their income your now taking all 100% at a 30% rate.
Let's assume a person's income/spending is at the poverty line (defined elsewhere), and they're paying no income tax at that level. Let's further assume the government introduces the FairTax, and the immediate effect is that prices on all new consumer goods rise 30%. Is the person worse off? No, because the prebate adds 30% to this person's income.
(In reality the price of domestic goods would rise substantially less than 30%, used goods would not be taxed, and I'm not entirely sure what would happen with rent and mortgage payments.)
Before I address taxation at other income/spending levels, I'd like to know your view on capital gains taxation. Tax is imposed on profits when an asset is sold, considering the actual price it was bought and sold. You don't take the price of the asset in between those points into account. The price a week before the sale could have been ten times higher or ten times lower, that doesn't affect the tax owed. Do you think this is a fair principle?
