Dont forget all the indirect tax people pay. VAT, council tax, road tax, insurance tax, airport tax, duty on alcohol and petrol, stamp duty,. Not sure how the proportion of tax compare once you have added in all of those, but my example of someone earning only just above the income tax threshold probably ends up paying a proportion nearly as great as the guy in the top 1%. Especially since I recall reading the richest are much more likely to arrange to be paid creatively and therefore avoid direct taxes. So it might be the guy at te bottom ends up paying more than the guy at the top as a percenage of his income. .
OK - let's look at indirect tax and the direction it has been taking.
VAT - you don't pay it on food, kids clothes and lower rates for house fuel etc. You don't pay it on rent.
Council tax - there is a sliding scale, and you don't pay it you get housing benefit and you pay less or half if you live alone or are elderly.
Road Tax - this has just changed. If you have a gas guzzler you pay over £500 a year and nothing if you have a small car. You also pay an extra road tax tax on new cars over £40K. It is a back door luxury vat rate.
Airport tax - not sure that the really poor would find this a problem, but again the rich pay a huge amount more.
Alcohol - again I'm not sure you can defend the social injustice here, but the more expensive your tipple, the more you pay.
Petrol - a problem for the rural poor. If TFL are an example of Corbinite transport costs then god help us.
Stamp Duty - did you miss that being changed to a sliding scale that kicks the crap out of property over around £900K
I think a lot of your examples reflect the concerns of the not rich in the South rather than what would be a problem for poor people elsewhere.
Since the crash, tax on richer people has gone up, with new taxes directed at them, whilst tax on the poor and lower paid has been brought down, see the tax allowance up to £12,500. I have never known the less well off pay so little tax in my life, and the better off pay more. These are the facts, but they don't fit the political rhetoric of JC.
