Obviously, no-one who is employed full time by the state pays any tax. Such a person is nothing but a 100% tax eater.
But some tax eaters are better than others.
State nurses may be chippy and refuse to clean MRSA off their hands, while state teachers may ruin young people's minds by filling their impressionable heads full of statist and environmentalist trash, but at least none of these people - I hope - would ever claim back from the taxpayer the five pounds they just put into a church charity box (presumably an action carried out to save face in public, rather than because it was meant in spirit).
But a British politician did.
Forget estate agents, journalists, and fractional reserve bankers. Is there any form of human life lower than a politician?
