Do everything you say Giok and the amount you take as revenue will plummet.

Now please explain to me what was iniquitous about the Community Charge. I will give you an example:

Four bedroomed house South coast of England.
Owner does not live there and has not done so for 12 years now
His children do, all are in employment, now counting the house-owner himself that is five incomes coming into that home.

Who pays the Council Tax - The absentee householder at full rate because there are more than two people in employment over the age of 18 living in the house. Note the householder is gaining no benefit at all from any service supplied by the Council.

Who would pay Poll Tax - The four people living there who are actually getting the "benefit" of the services provided by the Council.

Now tell me what is iniquitous about that?
