They say a picture is worth a thousand words.
This is the difference in income tax that people are paying in the current tax year versus what they paid under the last year of Labour government. When let's not forget they had had 13 years to align the tax rates in any way they wished with a large majority in parliament.
We can see that someone earning £10,000 is paying almost 30% less tax now whilst those earning the highest amounts (£500,000+) are paying well over 20% more. Oh, and that line above seems to me to be the dictionary definition of "progressive". It goes up progressively.
Worth remembering this next time Labour are banging on about how unfair the coalition is being to the poorest people.
Hattip to Len Gates and Carl Minns for the original data.
