That is true. There used to be tax concessions over here too for property owners but they are now long gone.
Sounds as if the cost base in Cambridge and East Anglia has gone through the roof these days. The hi-tech industry around the University is largely to blame. And most of the council tax seems to be now paying for welfare support and employees index-linked pensions.
With regard to the relative levels I am going by my recollections of up in Canada from some years back. Of course, the relative levels could well have changed since then. Certainly, the UK hasn't got cheaper.
Anyway, enough of my rant. Back to California.
