Some Musings on Tax

So, pace a discussion chez Timmy, a couple of graphs. Firstly, the distribution of UK after tax income in 2013-14:

Tax Year 2013-14, UK Govt Figures
At Richard's request, the same distribution for tax year 1999-2000:

Tax Year 1999-2000, UK Govt Figures

Then we have the %age change (NB: all positive), for each centile, in after tax income between tax years 1999-00 and 2013-14:
%age increase in income 2000-2014
Note that the above chart isn't corrected for inflation or anything else - raw figures from the data published here, as of the 1 Mar 2016 update. But Bank of England inflation figures state that inflation 2000 to 2014 was 50% (suspicious but true - check yourself) so, for clarity, the inflation adjusted graph is here:
Inflation Adjusted %age increase in UK after tax income, 2000-2014
