Why pigdog, I gathered that quote because you asked for it.
That surely indicates you think it is morally wrong for taxpayers to have charge of their own money and have any decision in when or how it should be taxed but that rather government should take in the funds and then allow the taxpayer whatever it decides is proper. You'll find that most FairTax supporters disagree with your view completely.
Say what? How did you get from an investment in infrastructure (that's stuff like highways, sewers, bridges) to morality? Show me a country that does not invest in infrastructure that is an economic success.
The answer should be obvious and the taxpayer is far better off (as is the government due to the more stable tax base) by having other resources to draw on if required.
Sure, even if I have to borrow more money to buy necessities and pay the 30% sales tax, interest and tax on the interest and financial services to keep money flowing to the government during a time I can't provide a living for myself and my family.
What was that you were saying about morality?
Actually there's no reason why you'd have to "buy necessities and pay the 30% sales tax" since a) there is no 30% sales tax, b) you will never have to bear more than the cost of the item plus your effective FairTax rate, and c) there is no "tax on interest on even should you borrow - and the rates at which you borrow will be reduced considerably from present rates.
