Hawker,
You seem incapable of distinguishing between taxation and spending. The collection of taxes is independent of the distribution of benefits. As I already pointed out, whatever you consider as equitable is possible with a sales tax.
I think it makes more sense to consider the economic ratifications of the tax system, and the social aspects of the spending.
A good point... collection is totally and completely separate from spending.
And you are certainly correct that a sales tax is by far the fairest tax there can be. It's almost COMPLETELY voluntary. If you don't want to pay taxes, don't buy anything.
And millionaires
certainly spend more on 'things' than a janitor does.
