The poll tax was a MUCH fairer sysem of tax than the old Rates and newer Council Tax.
The Rates meant those easy to find (ie those with houses) had to pay the rates, those with no houses, or who moved around in rented accomodation a lot, paid nothing, even though they used the services as well.
I bet it was not those in houses who were protesting back them, no it was the "great unwashed". Those who, for years, had used services they had never paid for, and were now protesting because someone was asking them to pay.
I still feel if the Tories had introduced the Poll tax on a gradual basis, over say a 10 year period, start the poll tax low and gradually increase it over that period, while reducing the rates, it may have worked.
Now we are stuck with the council tax, which is almost the same as the rates.
