Hmm, average income in the top decile is around £90,000 (no point in being more accurate than that throughout). Cut out everything they get from the State and everything they pay to the State and you get £65,000 a year. There are some 2.5 million households in that top decile.
So, total income of “the rich” is £225 billion a year, of which they pay £63 billion or so a year to the State (nett of course, taxes out and benefits in) leaving them with about £163 billion a year to wave in the faces of the downtrodden poor.
How much does the whole system cost a year? Around £660 billion isn’t it?
So, we could take all the money off the rich, every penny (and of course we could only do this once as the next year they’d all bugger off) and we’d be, umm, lessee….£660 minus about 60 they already pay minus another 160 ish that we let them keep so far….what, £440 billion short of what government costs us?
And that’s why we tax the poor, because the rich simply don’t have enough money to pay for the State we already have.
If you want to have a State that the poor don’t have to pay for, but the rich carry all the burden, then you need a smaller State than the one we have.
