Paying taxes on consumption makes no judgement whether it is 'good', 'bad', 'fair', or 'unfair' - nor should it. The "kpp_kpp_kpp_kpp" Tax is just that - a tax to raise revenue for the government - it takes no notice of your social circumstances ... and that's quite a good change from the present system which pretends to be the Mother's Milk of Happenstance throwing funds out willy-nilly. There's nothing 'fair' about that, either.
we both agree the word 'fair' is subjective. whew. excellent. :-)
