It was a trial local tax system. which based payments on the number of adults living at an address, rather than the value of the property.
I think it was a sound system, given we all have the same benefit from the things it paid for - local infrastructure, local services etc.
However, it seems that demands for equality only extent to "getting" and not when it comes to "paying".
it was first trialled in Scotland, where socialists managed to turn it into a classic left wing Scottish-grievance against the "bad English tooarreezz" who were supposedly inflicting misery on Scotland. (the same sentiments which sustain the SNP today).
Why should we contribute anything, they argued, instead the (typically unspecified) "rich" should pay for it all.
I think when it comes to income tax, certainly those who earn more should pay more (and naturally do), but when it comes to local services which give everyone the same benefit, we should all pay an affordable fair share.
I mean, we have got to give something back in return for our rights and citizenship, no?
The system has not been totally abandoned given, in modern Council Tax, single people living alone get a discount, but houses with 2+ adults living there pay a higher rate.
