That is barely matched by the increased contribution which London's Council Tax payers have had to hand over to Government for redistribution. You have fallen into the elementary error of thinking that people who live in big houses and who pay high Council Tax are rich. You know very well that that is untrue. You yourself have just indicated that a person is more or less able to demonstrate, by a level of income tax, their own individual wealth.
It is a crude weapon to suggest that just because somebody lives in a big house and who lives in an apparently wealthy area of London, is necessarily rich. There are very, very many poor people, particularly pensioners, who are being crucified by the Council Tax by your levy. This is absolutely outrageous and for you to sit there and say "Oh well, we are taxing the rich to help the poor" I remind you, Mr Mayor, that you do not make the poor rich by making the rich poor.
