In the UK there is an equivalent 'inheritance tax'. It is a grossly unfair tax in that it fails to tax the most wealthy. For instance the Grosvenor Estate of the Duke of Westminster recently passed an estimated $59bn company and $16bn in personal wealth to the next generation without paying any inheritance tax at all. This is a achieved by structuring as a trust fund. Yes anyone could start a trust fund, but not everyone can afford the professional fees.
