The maths in this article by Richard Murphy, The personal tax statement George Osborne doesn’t want you to see, is very clever, the analysis sharp, but the massive pie charts that try to illustrate the argument less so.
So all I’m adding are a couple of bar charts. But as Amanda Cox puts it, “Bar charts are like elevator conversation, they work for everything.” I think she meant it as a compliment. I’ve highlighted the three bars that Richard discusses in his article: the tax gap, the subsidy to the City of London and the implicit tax subsidy for home ownership. I leave you to decide which chart to choose.
Thanks to @MillerJoMiller for the spotting the article.
