I liked the idea of the poll tax. It would have been OK if the councils hadn't been allowed to put up their spending until it was established. Or local council increased the bills by ~25% with various claims that it was going to be expensive to collect, they wouldn't get more than 80% of it, etc. They didn't reduce it when the poll tax was scrapped or when they were collecting 97% of it.
The best bit was that even people on benefits had to pay some so if they wanted more spending they could vote for it but would have to contribute. Unlike now where they can vote for high spending knowing it will come from other peoples pockets.
The benefits were increased by enough to cover the average payments. They were not reduced when poll tax was scrapped, maybe its time they recovered the extra?
