Ok, so I got that wrong. But a tax on which everyone pays the same can't be said to be unfair.
Generally no matter the value of the property in which you live, you as a person still get the same provision of services from your local government. With the community charge the idea is that each adult paid the same amount for the same level of service provision. With the rates based system someone living in £100 000 house pays less than someone living in a £250 000 house. So the person living in the more expensive house pays more, yet recieves no extra service provision. Now you can argue that this is redistibution of wealth.
And yes I paid the community charge.
