With all the talk about businesses moving abroad to escape higher rate tax I've been wondering just what Britain does gain by being a major financial centre? I realise that there will be tax on those activities (does anyone know how much?). There will also be jobs created servicing those with a lot of money.
However there is also a downside - like the inflation in house prices and the encouragement of a consumer society.
Can anyone point me to a serious attempt to examine costs and benefits?
