Deal with the issue of international corporates paying v little tax. It is manifestly unfair and would affect fewer individuals than dealing with property tax. I also believe there are other issues behind our love of investment in property (eg wanting a tangible asset, not trusting in share release information) and other reasons for our property bubble (banks lending as much money as you like no matter what you earn). You won't fix these with property tax you'll just piss people off.
Do you like this suggestion?
