The salaries of some people (often sports 'stars', or heads of quangos, councils and large corporations) are obscene. If they decide to live abroad where taxation is less, so be it – many of them spend their money abroad in any case. Footballers' salaries are a good case in point.
A supertax bracket of 75% (or more) should be introduced for incomes above £10,000 a week which should go directly to organisations like the NHS.
Recipients of such huge salaries could get relief from the tax on any money they give directly to charity.
